Note that PostgreSQL 9.5 iand above s required for this solution, but it should provide most of what you need.* *If you go to http://stackoverflow.com/questions/23488228/how-to-get-sql-text-from-postgres-event-trigger/35616026 <http://stackoverflow.com/questions/23488228/how-to-get-sql-text-from-postgres-event-trigger/35616026>* *and scroll toward the bottom, you will see an example of how to trap object mods. * *Additional info as to what else can be captured is detailed in https://www.postgresql.org/docs/9.5/static/functions-event-triggers.html <https://www.postgresql.org/docs/9.5/static/functions-event-triggers.html>* *You can also use now() or transaction_timestamp(), etc to record the date/time the change occurred.* *Finally, although the schema_name is provided in pg_event_trigger_ddl_commands(), you will need to * *SELECT relname FROM pg_class WHERE relnamespace IN (SELECT oid from pg_namespace WHERE nspname = schema_name) INTO tbl_var;**just to *get the table name. I'm not sure why they didn't just give the table name firectly, but hey, at least there is a solution -- *Melvin Davidson* I reserve the right to fantasize. Whether or not you wish to share my fantasy is entirely up to you.
