Release Notes:
https://github.com/pgvector/pgvector/blob/master/CHANGELOG.md#081-2025-09-04

Now supports PostgreSQL 18.

Those extensions don't support building with PostgreSQL 18, yet.

To make sure the broken status is updated on the next upgrade, they all
have version checks in the form of an evaluation warning, so that there
has be explicit action regarding its PG18 compatibility.

Thanks, deadnix.

This is for consistency with postgresqlTestExtension and
postgresqlTestHook. Everything that is passed via postgresql's
generic.nix "packages scope" now is prefixed with "postgresql".

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.

Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.

A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
