Support Postgres vector data types

[uw4]

When storing embeddings in pg vector we get these warnings:

2024-07-07 18:20:47,572 INFO [org.das.ser.Services] (executor-thread-161) Starting metadata collection for tenant=null

Tested with dockerhub container pgvector/pgvector:pg16

Not critical as the table can still be browsed read-only:

Typical stacktrace during browsing:

2024-07-09 18:30:50,839 INFO [org.das.ser.ExMapper] (executor-thread-167) REST exception: org.postgresql.util.PSQLException: ERROR: operator does not exist: bigint = character varying
Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
