Add error codes to a few errors ( #657 )
...
With elog(), you get XX000 "internal_error", which sounds scary.
It's not self-evident what the right error codes for some of these
errors are, but I tried to use my best judgment.

Swap max costing values to align with upstream guidance ( #658 )
...
A feature targeted for PostgreSQL 18 (postgres/postgres@e2225346 )
that makes optimizations around disabled path nodes impacted pgvector
such that PostgreSQL would choose to perform an index scan when it
should have used a different scan (e.g. `SELECT count(*) FROM table`).
Per upstream guidance[1], the recommendation is to switch to using
`get_float8_infinity()`, which achieves the same behavior in backbranches,
and can be adapated to work with the new behavior introduced in PostgreSQL 18.

Fix init_fork WAL-logging on unlogged indexes ( #591 )
...
Currently pgvector does not create any WAL records for unlogged tables
Postgres assumes INIT_FORK of unlogged tables is persistent and uses it
to reset the table index to its default empty state after a server
crash.
This patch makes INIT_FORK of unlogged table WAL-tracked, which ensures
an unlogged table is usable after a crash-restart
