Create or replace trigger postgres

Question

I want to \"create or replace\" a trigger for a postgres table. However, there is not such sql expression.

I see that I can do a \"DROP TRIGGER IF EXISTS\"

Answer 1

Postgresql has transaction DDL so BEGIN > DROP > CREATE > COMMIT is the equivalent of CREATE OR REPLACE

This is a nice write-up of how postgre's transactional DDL compares to other systems (such as oracle)

Current postgres planned features regarding triggers do not include adding the REPLACE syntax.
