Feature request: Support Postgres event triggers #7570

Open danieltprice opened 3 months ago

danieltprice commented 3 months ago

Add support for event triggers to capture DDL events: https://www.postgresql.org/docs/current/event-triggers.html

We currently do not support event triggers due to the superuser requirement.

Integration partners need to capture DDL events and use EVENT TRIGGERS to listen for them. Is it possible that, instead of trying to allow for event triggers completely, we offer a specific function to register for DDL events of a table. Partners need the DDL events, not necessarily the event triggers.
