Alpine no longer provides versioned postgresql*-pgvector packages for older Postgres majors and the unversioned package pulls PG18 by default.
This builds pgvector from source against the base image Postgres to keep Alpine images working across all supported versions.

@JordiMForgeFlow could you take a look?
Since you proposed adding pgvector, this PR fixes Alpine builds where postgresql-pgvector now pulls the default PG18 and breaks older Postgres images by compiling pgvector from source instead.

You can see in the scheduled workflows that is not longer building when PG>=14 https://github.com/Tecnativa/docker-postgres-autoconf/actions/runs/20200691866
