Hi, does sql-db allows to capture PostgreSql notify events?. If yes,
how?.

Indirectly. You have to set it up using the TPQConnection.Handle since this has long-term persistence, and have to make direct API calls *not* ExecuteDirect() since that uses a temporary handle. It works, but is sensitive to transient network failures etc.: the server end can forget, so it's wise to have a fallback mechanism.

I don't know whether it should be treated as a candidate for an extension to the sql-db API, since as far as I know there's something comparable (implemented very differently) on Firebird but nothing else.
