Trying to get some DDL auditing in a development environment by adding triggers
to pg_proc, pg_class,pg_type,pg_trigger and getting the following error:
ERROR: permission denied: "pg_proc" is a system catalog
SQL state: 42501
Is there any way to achieve DDL auditing in Postgres and trace any
new/dropped/changed object into a table? All I need is to at least be able and
save a userid(current_user), timestamp, action, and the name of the object and
this could be done easily by adding triggers to these pg catalogs.
