You are probably referring to "DDL" triggers and similar things (a trigger when a table is created or dropped, a user
logsin and so on). 

The answer is no as far as I know.

Postgres 9.3 will add "event triggers", but they can only be written in SQL

That should have been: "only C and procedural languages like PL/pgSQL"
