Consider adding support for pgvector & pgvectorscale for PGSQL

[robi]

Since we still don't have Multi Cloudron and many AI front and apps, these extension(s) to the existing Postgres DB on Cloudron would benefit many.

See: https://github.com/timescale/pgvectorscale

Consider enabling these for all, or at least a check box way to enable them.

pgvector and pgvecto.rs are both already integrated and enabled as extensions with the current postgres addon.

Amazing, thanks for confirming!
