This adds two new features to pgroles:

  1. Global default privileges: Default privileges can now be defined globally for a role instead of for a particular schema using a new scope field, which replaces the previous schema field (which is still supported).
  2. PUBLIC grantees: Grants and default privileges can now be specified as applying to the PUBLIC "pseudo-role", which is treated by Postgres similarly to a role which every role is a member of. PUBLIC-grantee grants and default privileges are treated somewhat differently by pgroles, as many are automatically created by Postgres (e.g. CONNECT on databases) and users probably don't want these to be removed during reconcilation. Therefore, a new ensure field is added on grants and default privileges which can be set to either present or absent; PUBLIC grants will only be revoked if an explicit ensure: absent rule is present. Unlike other grants, removing a PUBLIC grant from a pgroles policy will not automatically revoke the corresponding grant, and similarly for default privileges.

📝 Walkthrough

Walkthrough

The change adds typed PUBLIC handling, ensure: absent assertions, global and schema-scoped default privileges, bundle-plan v2 keys, approval encoding v3, and executor-authority preflight checks. It updates reconciliation, inspection, SQL generation, CLI workflows, operator reconciliation, schemas, tests, and documentation.

Diff and dry-run paths report authority warnings. Apply and operator reconciliation block execution when authority is insufficient. Plan summaries include global default-privilege counts.
Approval encoding and schemas
crates/pgroles-core/src/approval.rs, crates/pgroles-operator/src/plan.rs, charts/pgroles-operator/crds/*, k8s/crd.yaml, k8s/postgrespolicycandidate-crd.yaml
Approval effects now use encoding v3. CRDs support ensure assertions and explicit global or schema default-privilege scopes.
Usage documentation and examples
docs/src/pages/docs/*, examples/security-definer-api.yaml, skills/pgroles-policy/SKILL.md, CHANGELOG.md
Documentation and examples describe absence assertions, PUBLIC rules, scoped defaults, authority preflight behavior, and bundle-plan changes.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to ab856

The new global default-privilege and PUBLIC-grantee behavior still has unresolved correctness issues: some revocations may be inverted or silently dropped, certain object types may fail to converge, and some plan workflows may degrade without producing a reviewable plan. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Reject ensure: absent in profile grants

ProfileGrant has no ensure field, and unknown fields are ignored. Thus, ensure: absent is ignored while expansion emits Ensure::Present. Reject this input with the same additive-template rule used for profile default privileges.

218-226: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Flag ensure: absent default-privilege grants as unrepresentable.

role_dps collects every entry of dp.grant without checking ensure. build_profile then hardcodes ensure: Ensure::Present at line 1080, so a schema-scoped ensure: absent default privilege is folded into a profile as a present assertion.

check_round_trip catches the inversion, because the original graph holds the key in default_privilege_absences while the candidate holds it in default_privileges. The result is RoundTripFailure and the entire suggestion run returns the input manifest.

That is the outcome the comment at lines 305-309 states the guard prevents. Object grants have the guard at line 310; default-privilege grants do not. Add the matching check so only the affected role is skipped.

🐛 Proposed fix: treat absent default privileges like absent grants

Track the affected roles while bucketing:

     for dp in &input.default_privileges {
         // Profiles are schema-scoped, so only schema-scoped entries can be
         // folded into one; global entries stay as-is.
         let Some(schema) = dp
             .resolved_scope()
             .ok()
             .and_then(|scope| scope.schema().map(str::to_string))
         else {
             continue;
         };
         let owner = dp
             .owner
             .clone()
             .or_else(|| input.default_owner.clone())
             .unwrap_or_default();
         for grant in &dp.grant {
             if let Some(role) = &grant.role {
+                // Profiles cannot express `ensure: absent`; expand_manifest
+                // rejects it outright. Folding such a rule would silently
+                // invert it to `present`.
+                if grant.ensure == crate::manifest::Ensure::Absent {
+                    absent_default_privilege_roles.insert(role.clone());
+                }
                 role_dps.entry(role.clone()).or_default().push((
                     owner.clone(),
                     schema.clone(),
                     grant.clone(),
                 ));
             }
         }
     }

Declare the set next to role_dps:

let mut absent_default_privilege_roles: BTreeSet<String> = BTreeSet::new();

Then reject those roles alongside the existing global-scope check:

         if role_has_global_default_privilege(input, role_name) {
             skipped.push(SkipReason::UnrepresentableGrant {
                 role: role_name.clone(),
             });
             continue;
         }
+        if absent_default_privilege_roles.contains(role_name) {
+            skipped.push(SkipReason::UnrepresentableGrant {
+                role: role_name.clone(),
+            });
+            continue;

Drop the now-dead default_owner fallback argument from validate_ensure_conflicts.

Lines 921-925 normalize owner from manifest.default_owner before validation runs. After that loop, validate_ensure_conflicts receives manifest.default_owner and applies .owner.as_deref().or(default_owner) at line 1216. That .or(...) can no longer change the result, because every entry with a resolvable owner already carries it. Only the unwrap_or("postgres") branch stays reachable.

Remove the parameter so the normalization stays the single source of the owner. This also removes one of the two places that spell the "postgres" fallback; the other is RoleGraph::from_expanded in crates/pgroles-core/src/model.rs.

Add the owner to the two scope-shape errors.

DefaultPrivilegeScopeSchemaMissing and DefaultPrivilegeScopeSchemaForbidden carry no locator. The sibling variants DefaultPrivilegeScopeConflict and DefaultPrivilegeScopeMissing both name owner. A manifest with several default_privileges entries therefore gives the user no way to find the offending entry from the message alone. resolved_scope() already builds an owner_context() closure, so the value is available at both call sites.

♻️ Proposed error-message change
-    #[error("default privilege scope of type `schema` needs a `schema` name")]
-    DefaultPrivilegeScopeSchemaMissing,
+    #[error(
+        "default privilege entry for owner \"{owner}\" uses scope type `schema` but names no `schema`"
+    )]

The test default_privilege_scope_must_be_specified_exactly_once matches only on the variant, so it keeps passing.

Extract the (global) scope label so the two render paths cannot diverge.

build_visual_graph and default_priv_node_id both spell key.scope.schema().unwrap_or("(global)"). The node label and the node id must agree for a reader to connect them. A change to one literal would silently desynchronize the two.

Add a round-trip test for global scope.

round_trip_export_import covers only the schema shorthand. The global branch at lines 151-157 is the new path: it must emit scope: {type: global} and no schema, and resolved_scope() must map it back to DefaultPrivilegeScope::Global. Nothing asserts that today.

This test does not reach the grant-key collision path it describes.

The test name says two fragments may not split one assertion. The assertion checks DuplicateManagedSchemaFacet, and the comment states the facet check fires first. So the new dedup and collision logic at lines 448-455 is never exercised for a cross-document present-versus-absent pair.

Add a case that uses a grant with no schema facet, so the grant key itself is the only claim. A database grant works, matching the existing compose_bundle_rejects_duplicate_grants test.

Add a unit test that pins the absence-map routing.

RoleGraph::from_expanded now routes privileges into grants or grant_absences, and into default_privileges or default_privilege_absences, based on Ensure. No test in this module asserts that routing. The existing tests cover only the present path.

A direct test protects the invariant that the two maps stay disjoint per privilege and that one key can appear in both maps with disjoint privilege sets.

Pin the v2 shape change, not only the version string.

The version bump exists because ManagedOwnershipKey::DefaultPrivilege now serializes a tagged scope object instead of a schema string. This test composes a bundle that contains only a role, so the plan holds no default-privilege change and no assertion covers the new shape.

Extend the fixture with a default-privilege rule and assert the serialized scope. Then the test fails if the shape regresses, which is the change the version string promises.

Confirm the kind tag value and the managed_key serde attributes before applying; the snippet assumes the existing kind tagging shown by the "role" assertion.

.ok() drops a DefaultPrivilegeScopeConflict or DefaultPrivilegeScopeMissing error, so a malformed entry is skipped without a SkipReason.

Extend the corpus to reach the new suggester decision paths.

random_manifest emits only Ensure::Present and only schema-scoped default privileges. The suggester gained three new rejection paths in this PR: absent grants, global-scope default privileges, and absent default privileges. This generator cannot reach any of them, so the existing round-trip and idempotence properties cannot detect a regression there.

Occasionally emit Ensure::Absent grants and scope: Some(DefaultPrivilegeScopeSpec { scope_type: Global, .. }) entries. The round-trip property then asserts that such roles stay flat instead of being folded.

This pairs with the missing absent default-privilege guard I raised on crates/pgroles-core/src/suggest.rs.

Consider indexing the two per-row lookups.

The logic is correct. Both lookups are linear scans inside the row loop: scopes.iter().any(...) for PUBLIC coverage and managed_roles.contains(...) for role grantees. The cost is O(rows × scopes) plus O(rows × managed_roles), and row count grows with managed schemas times object types times grantees.

Build a BTreeMap<(String, Option<String>, ObjectType), &BTreeSet<Privilege>> from scopes and a BTreeSet<&str> from managed_roles before the loop. That keeps the deterministic-collection rule and removes both scans.

This is an inspection path that runs once per reconcile, so it is a throughput improvement rather than a fix.

Do not block plan generation on executor authority.

This check runs before the PolicyMode::Plan branch at Line 1069 and before manual-approval plan creation at Line 1609. Neither path executes SQL. A policy whose executor lacks owner authority therefore produces no PostgresPolicyPlan at all and goes Degraded, so operators cannot review the pending change. The CLI takes the opposite approach: preflight_authority warns for diff and blocks only where SQL runs.

Log the issues in the non-executing paths, and return ExecutorAuthority only before execute_plan.

ftxqxd added 2 commits August 17, 2026 01:17
PostgreSQL keeps default privileges in two layers. The schema layer,
which pgroles already managed, adds privileges for one schema. The global
layer applies to every schema an owner creates objects in, including
schemas no policy manages, and it is the only layer that can change what
PostgreSQL applies by default.

`default_privileges` entries now accept `scope: {type: global}` beside
the existing `schema:` shorthand, which stays valid and is still what
export emits for schema-scoped rules. An entry must set exactly one of
the two. Global scope renders ALTER DEFAULT PRIVILEGES with no IN SCHEMA
clause and additionally allows `on_type: schema`; schema scope does not,
since a schema is not contained in another schema. `on_type: database`
is rejected everywhere because PostgreSQL has no such defaults, and
views are rejected in favour of `table`, which is how pg_default_acl
records them.

Inspection reads the global layer for exactly the (owner, object type)
pairs a manifest declares, reporting the effective default: where no
explicit pg_default_acl row exists, acldefault() stands in, so a fresh
database compares against what PostgreSQL will actually apply rather
than against nothing. Owner self-entries are excluded in SQL. Every
ALTER DEFAULT PRIVILEGES materializes the owner's implicit self-grant
into the stored row, and reporting it would make authoritative mode
revoke the owner's own default on the next reconcile.

Because a global rule reaches the whole database, only the bundle
document that owns the owner role may declare one, and `diff` counts
global changes on their own line so they are visible in a plan.

Bundle plan JSON moves to pgroles.bundle_plan.v2: default-privilege
changes and their ownership keys carry a tagged scope instead of a bare
schema string, which could not express a global rule.
PostgreSQL grants EXECUTE on every function to PUBLIC without writing an
ACL entry, so no combination of positive grants could take it away. A
SECURITY DEFINER routine stayed callable by every role no matter what the
manifest said.

Grant entries and default-privilege entries now accept `ensure: absent`,
which revokes a privilege where it is held, and `role: PUBLIC` addresses
the pseudo-role. Pairing an object-level absence rule with a global
default-privilege one covers both the objects that exist and the ones
created later.

PUBLIC is typed as a Grantee rather than spelled as a magic string, so
SQL rendering can never quote it and a role whose name resembles the
keyword can never be confused with it. Inspection reports PUBLIC's
effective privileges, synthesizing acldefault() where the ACL is still
NULL, so a fresh database plans the revoke it needs.

PUBLIC is reconciled only where a rule names it, in every mode. A PUBLIC
privilege no rule mentions is never revoked: databases are full of grants
extensions and PostgreSQL itself created, and revoking them wholesale
would break what pgroles was never asked to manage. The consequence is
that deleting a `present` PUBLIC rule does not revoke it — the rule has
to become `ensure: absent`.

additive silently ignores absence assertions since it never revokes;
adopt and authoritative apply them. Declaring the same privilege both
present and absent is rejected during validation, including across a
wildcard and a named selector, where grant-before-revoke ordering would
otherwise flap forever.

Preflight reports planned default-privilege changes and PUBLIC revokes
the executor lacks authority for. It warns on diff and dry runs, which
execute nothing, and blocks the real apply. A PUBLIC revoke issued
without the owner's authority silently changes nothing, so the
controller would otherwise re-plan it forever.

ftxqxd force-pushed the feat/public-ensure-absent-global-defaults branch from 8da5024 to 36a77e6 Compare August 17, 2026 01:33
Executor authority no longer blocks planning. The check ran before the
observe-mode branch and before manual-approval plan creation, neither of
which executes SQL, so a policy whose executor lacked owner authority went
Degraded with no plan for anyone to review. The issues are logged instead,
and the error is returned at the two points where a plan would execute.

Preflight asked the database for more objects than the planned statement
can reach. The relation query matched every relkind whatever the object
type named, and the type query returned array types and the composite type
every table carries. A wildcard target accepted all of them, so objects the
revoke could never touch raised blocking issues.

acldefault does not share an alphabet with pg_default_acl. It reads `S` as
a foreign server and spells a sequence `s`, so the stored character cannot
be passed straight through. Nothing observable changed, because a sequence
has no PUBLIC default either way and the owner filter drops the rest.

A global default privilege that omits `owner` resolves to `default_owner`,
but claimed no role at all, so two policies could both manage the same
owner without conflict detection noticing.

PUBLIC produced grant and default-privilege edges pointing at `role:PUBLIC`,
a node nothing creates, since a managed role can never carry that name. It
now gets an unmanaged node like membership members that name no role do.

Two diagnostics read wrong once the values became typed. The scope renders
its own noun, so the template added a second one, and PUBLIC was labelled
and quoted as though it were an ordinary role.

Profile default privileges accepted no `ensure`, so Kubernetes pruned
`ensure: absent` and the conversion applied Present. Top-level entries
already carried the field.

The scope rules are now also CEL, so the API server rejects an entry
setting both `schema` and `scope`, neither, or a global scope naming a
schema, instead of leaving it to manifest expansion.

2225-2239: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider reusing the core PUBLIC predicate instead of the string literal.

Both filters compare against the literal "PUBLIC". The core crate owns the PUBLIC grantee semantics (exact-uppercase PUBLIC). If the core rule changes, these two sites drift. Expose a helper or constant in pgroles_core and call it here.

…coding

A database-level PUBLIC rule names no schema, and PUBLIC cannot be claimed
as a role, so it claimed nothing at all. Two policies could assert opposite
states for the same PUBLIC privilege on one database and never be seen as
conflicting. Database grants to a named role stay unclaimed, so two teams
granting CONNECT to their own roles still do not collide.

The canonical effect encoding carries a default-privilege scope as a tagged
value now, which is a change to how effects are normalized, so it takes a
new constant. Plans written under v2 stop being comparable and supersede
once, which is the fail-closed direction the constant exists to force.

diff --format json changed shape the same way bundle output did, but it has
no version field to announce it, so the changelog says so and marks the
output unstable.

- **BREAKING: the approval digest encoding is now `pgroles.io/approval-effect/v2`**, which binds the target identity above.
**Upgrade:** on the first reconcile after upgrading, every open plan is superseded and replaced by an equivalent plan under v2, and recorded decisions do not carry over — open plans need one fresh approval. Nothing executes in the meantime. Deliberately, a `pg_upgrade` (fresh `system_identifier`) or a blue-green cutover also moves the identity and invalidates any approval open across it; re-approve the fresh plan afterwards. (#180)
- **BREAKING: the approval digest encoding is now `pgroles.io/approval-effect/v3`.** v2 binds the target identity above, and v3 additionally carries a default-privilege rule's scope as a tagged `scope` value instead of a bare `schema` string, which could not express an owner-wide rule.
**Upgrade:** on the first reconcile after upgrading, every open plan is superseded and replaced by an equivalent plan under v3, and recorded decisions do not carry over — open plans need one fresh approval. Nothing executes in the meantime. Deliberately, a `pg_upgrade` (fresh `system_identifier`) or a blue-green cutover also moves the identity and invalidates any approval open across it; re-approve the fresh plan afterwards. (#180)
