 | 2026-09-04 | SingleStore Connector/ODBC | [memsql/singlestore-odbc-connector#45](https://github.com/memsql/singlestore-odbc-connector/issues/45) | `SQLGetTypeInfo` fails `42S22 Unknown column 'json' in 'field list' (1054)` whenever `sql_mode` contains `ANSI_QUOTES`: the type-info result set is built from a template with double-quoted string literals (`ma_info.c`), which that mode turns into identifiers. `SQLTables`/`SQLColumns`/queries unaffected; MySQL Connector/ODBC fine on the same server. | **fixed** — **fix PR [#48](https://github.com/memsql/singlestore-odbc-connector/pull/48) (ours)**, opened 2026-09-17, approved and merged 2026-09-23 by the maintainer (Pavlo Mishchenko), merge commit `182ae5b515`, closing the issue the same minute: single-quoted literals in the template, with a test under `ANSI_QUOTES`. Verified against SingleStore 9.1.1, and the driver was rebuilt from the merged branch here on 2026-09-23 with the whole `info` suite green in both the client-side and the server-side prepared-statement modes. Review asked for the test to run on its own connection, following the project's `odbc143`, and to restore `sql_mode` before disconnecting; both landed in the second commit. Not yet in a release: `master` is still 1.2.2, so the shipped-in line waits for the next tag |
 | 2026-09-05 | ArcadeDB | [ArcadeData/arcadedb#7178](https://github.com/ArcadeData/arcadedb/issues/7178) (opened by the maintainer from the [discussion follow-up](https://github.com/ArcadeData/arcadedb/discussions/6888#discussioncomment-18309009)) | The Arrow native PostgreSQL ADBC driver cannot connect to ArcadeDB's PostgreSQL-protocol plugin: its type-resolver bootstrap `SELECT oid, typname, typreceive, typbasetype, typrelid, typarray FROM pg_catalog.pg_type WHERE …` is answered with zero columns (`Expected 5 or 6 columns from type resolver pg_type query but got 0`), because the emulated `pg_type` knows neither `typreceive` nor `typsend` and its WHERE parser accepts only a single equality. Found by the 2026-09-05 native-driver probe; the maintainer's own diagnosis is in the issue. | **fixed on main**: [ArcadeData/arcadedb#7179](https://github.com/ArcadeData/arcadedb/pull/7179), opened by the maintainer the same day and merged 2026-09-06 (558e6042); ships in ArcadeDB 26.10.1 (October 2026, per the maintainer) and is in `26.10.1-SNAPSHOT` now. Verified on the PR's CI build with the fixture types present: the native driver connects and `GetObjects` lists the types; with the driver's defaults it then stops at the first result set because ArcadeDB has no `COPY (…) TO STDOUT (FORMAT binary)` (the CockroachDB, CrateDB and YDB stop); with `adbc.postgresql.use_copy=false` reads work end to end and only `GetTableSchema` (its `$1::regclass::oid` lookup) returns an empty schema. Follow-up issue [#7180](https://github.com/ArcadeData/arcadedb/issues/7180) carried the driver's exact statements; its `GetTableSchema` item (the `::regclass` cast) is **fixed in [#7187](https://github.com/ArcadeData/arcadedb/pull/7187)**, merged 2026-09-06 (ec871770), verified on its CI build: five and eight fields with the right Arrow types. Binary `COPY` was tracked as [#7188](https://github.com/ArcadeData/arcadedb/issues/7188), implemented in [#7398](https://github.com/ArcadeData/arcadedb/pull/7398) on 2026-09-10 and framed like PostgreSQL's in [#7607](https://github.com/ArcadeData/arcadedb/pull/7607) on 2026-09-15; with all three, the native driver passes the whole probe with its defaults on `26.10.1-SNAPSHOT`. |
 | 2026-09-06 | ArcadeDB | [ArcadeData/arcadedb#7188](https://github.com/ArcadeData/arcadedb/issues/7188) (opened by the maintainer from the probe follow-up) | `COPY (<query>) TO STDOUT`, text and binary, is not supported by the PostgreSQL-protocol plugin; the Arrow native PostgreSQL ADBC driver reads every result through binary `COPY` by default, so with defaults it stops at the first result set. The driver's `adbc.postgresql.use_copy=false` statement option reads through ordinary binary-format results and works end to end on ArcadeDB, which the issue records. | **fixed on main**: [ArcadeData/arcadedb#7398](https://github.com/ArcadeData/arcadedb/pull/7398) (merged 2026-09-10) implemented `COPY (<query>) TO STDOUT` in text, csv and binary on both protocol paths; the one framing detail left between it and the Arrow driver's default path (the binary header sent as its own `CopyData` message, [reported](https://github.com/ArcadeData/arcadedb/issues/7188#issuecomment-5647328956) with both servers' chunk dumps on 2026-09-12) was fixed by the maintainer in [ArcadeData/arcadedb#7607](https://github.com/ArcadeData/arcadedb/pull/7607), merged 2026-09-15 (3bdb3451b). Verified the same morning on `26.10.1-SNAPSHOT` build 99f4cb48: the Arrow PostgreSQL ADBC driver 1.12.0 with its defaults passes all seven probe steps and decodes real rows (int64, string, double, date32, bool) through binary COPY, no `use_copy=false` needed. The maintainer closed the issue on 2026-09-15; re-verified the same day past the probe — an empty result set (header and trailer with no rows, the case the fix names), one row, 10,000 rows in one `COPY`, a NULL in every column, non-BMP text, `GetTableSchema` and `GetObjects` — all correct with the driver's defaults. Ships in ArcadeDB 26.10.1 |

 | 2026-09-21 | ArcadeDB | [ArcadeData/arcadedb#8090](https://github.com/ArcadeData/arcadedb/issues/8090) | A `DATETIME_MICROS` (also `DATETIME_NANOS`, `DATETIME`) value written as a string with a space separator **and** a fractional second — `'2024-02-29 13:45:10.123456'`, exactly the form psqlodbc renders a bound timestamp in — is stored as `NULL` while the `INSERT` reports success. Either half alone is fine: the `T` separator round-trips, and the space form without a fraction round-trips. Carried into the project's own tracker by a maintainer after we documented it in the compatibility notes, with the root cause named: a blanket catch in `Type.convert()` logs at `FINE` and returns `null`. Every PostgreSQL-wire client that binds a timestamp against a sub-second property is affected, not only this driver | **fixed** in [#8096](https://github.com/ArcadeData/arcadedb/pull/8096), merged 2026-09-22 by the project (Luca Garulli), who had filed the issue on 2026-09-21 as `severity:critical`, crediting the report and naming the root cause. The space-and-fraction form is now accepted, and a value no parser can read fails the write with an error naming it instead of storing `NULL`; reads stay lenient and return `NULL`. Verified here on `26.10.1-SNAPSHOT` (build `382ae09d`, 60 commits past the merge) on 2026-09-22: the literal and the bound parameter both round-trip to the microsecond, an unreadable value raises SQLSTATE 22023 through psqlodbc, and the column now reaches Arrow as `timestamp[us]` rather than a string. Awaiting the 26.10.1 release. ArcadeDB published an account of this and the three earlier findings on 2026-09-21: [arcadedb.com](https://arcadedb.com/blog/arcadedb-apache-arrow-adbc-postgresql-wire/) |
