The problems I see are - you won't catch DDL statements issued in a function with that, since you only see the top-level statement - if you have the DDL statement as string, you need to parse it, which is non-trivial > Can you please help me with the event trigger in C? & also how can we > integrate it with our current postgresql DB? In an e-mail, I cannot do much beyond pointing you to the documentation: https://www.postgresql.org/docs/current/event-trigger-interface.html There is also a simple example: https://www.postgresql.org/docs/current/event-trigger-example.html Getting used to reading and writing PostgreSQL server code takes a while.
