Flag any hunk not needed for the stated + purpose. After the patch, the code should read as if it had always been + written that way. +2. **Atomic, bisectable commits.** Each commit must build and pass tests on its + own — a broken intermediate commit breaks `git bisect`, revert, and + cherry-pick. Flag a commit that only compiles once a later commit lands. + Prefer one focused patch, or a clearly-ordered series of + independently-committable pieces. +3. **Tests + docs are mandatory.** A user-visible change without regression/TAP + tests **and** documentation is WIP, not commit-ready. New behavior needs + tests that cover edge and error paths, not just the happy path. +4. **DRY / reuse.** Prefer existing infrastructure (`List` in `pg_list.h`, + `StringInfo`, `dynahash`/`simplehash`, `palloc`/`MemoryContext`, `foreach`) + over reinventing it. Flag copy-paste and speculative abstraction alike — the + community wants minimal, targeted changes that fit the subsystem's existing + patterns. +5. **Whitespace.** No trailing whitespace; tabs (width 4) for C indentation; + `git diff --check` must be clean.

Each carries a `Node *` value that + downstream parse-analysis would convert into a PG plan tree. + - **Multi-statement productions**: 13 new rules covering five QUEL + statement forms (`RETRIEVE`, `REPLACE`, `APPEND`, `DELETE`, + `RANGE OF … IS …`). + - **Precedence directives**: 4 `%nonassoc` markers placing the QUEL + statement keywords at level 1000 (well above SQL's ladder which + occupies 1–99) so QUEL and SQL operator precedence cannot + interfere with each other. + - **Cross-statement integration**: `stmt ::= quel_stmt` glues the + QUEL extension into the base grammar's start symbol. No + modifications to the base SQL grammar. + - **Reduce-callback dispatch**: every QUEL rule has a `quel_reduce` + callback that fires via `pg_grammar_ext_dispatch_reduce` from + the rebuilt parser .so. + +## Subset of QUEL implemented + +``` +range of e is emp +retrieve (e.name, e.salary) where e.dept = "shoe" +retrieve into expensive (e.name, e.salary) where e.salary > 50000 +append to emp (name = "alice", salary = 1000, dept = "toy") +replace e (salary = e.salary * 1.1) where e.dept = "shoe" +delete e where e.salary < 1000 +``` + +The grammar accepts these shapes; the reduce callbacks emit `NOTICE` +messages identifying which production fired.
