pgsearch (https://github.com/paradedb/paradedb/tree/dev/pg_search) is a Postgres extension that enables full text search over heap tables using the BM25 algorithm.

The docs don't mention it at the time of this post: https://docs.render.com/postgresql-extensions

As many companies #justusepostgres it would be very helpful to have something like pgsearch supported by Render.
