Thank You Depesz. This will work for ‘CREATE’ and ‘DROP’ DDLs.
But, what about the scenario where I want to just have event triggers for operations like these? - 'ALTER TABLE','ALTER TRIGGER', 'ALTER FUNCTION'
Sure - just check differences in appropriate catalogs. pg_attribute, pg_trigger, pg_proc.
In any way - if you want to really use it - you'll have to write in C.
