Using a connection pool in each module is hardly efficient: Even with a relatively small number of modules, and a small pool size in each, you end up with a lot of server processes. You either need an extra server (or 3), or your database server(s) must have enough resources to support a connection pooler, in addition to PostgreSQL.
