adbcBridge v0.1.2

adbcBridge 0.1.2

One behaviour change on PostgreSQL. Columns declared with reduced precision now read at that precision: TIMESTAMP(0) / TIMESTAMPTZ(0) as timestamp[s], TIMESTAMPTZ(1..3) as timestamp[ms, tz=UTC], TIME(0) as time32[s], TIME(1..3) as time32[ms]. Values are unchanged; only the Arrow unit is, and it now matches the column. Code that assumed every PostgreSQL timestamp arrives as microseconds sees the declared unit instead. Every other database keeps its exact behaviour. (#107)

Also on PostgreSQL (#107): bulk ingest creates the column the Arrow type says, TIMESTAMP(n) for a zone-less timestamp and TIMESTAMP(n) WITH TIME ZONE for a zoned one, TIME(n) for every time unit; adbc.connection.db_schema answers the current schema (also on DuckDB); GetObjects at schema depth names the catalog. The ADBC Driver Foundry validation suite now passes 293 of 327 on PostgreSQL, the remaining 34 being declared PostgreSQL limits such as nanosecond precision; details in tests/validation/RESULTS.md.

Windows fix (#109): PostgreSQL bulk ingest bound its array literals as narrow text, so non-ASCII text stored through psqlodbc on Windows was double-encoded (héllo landed as héllo). The literals are now bound wide, as the row path always was. psqlodbc also receives LFConversion=0 on Windows, so fetched text keeps the newlines the server stored instead of CR LF.

Verified on Linux, macOS and Windows before the tag (PR descriptions carry the per-platform runs). A PostgreSQL job now runs in CI against a real server on every push.
