I already tried pgaudit ;), one of the best examples, it helped me much.

The module i'm thinking of, working on, is a bit inspired from pgaudit
and petere's pg_trashcan.
It should copy every created table in a "shadow"-schema with extra
columns for record on / record off and Userid (this is already working ;)).
In case of a drop statement it should rename the table in the shadow
schema XXX-droped-Date.

Now i am trying to catch the planned Stmts, ...
It should work without triggers - because the shadow schema should only
be visible for user postgres.
