As a matter of course I include fields to record the timestamp and user
for insert of records and last update of record on my tables.
For a relatively simple solution see this blog post I put up this summer:
http://aklaver.org/wordpress/2012/06/23/postgres-and-hstore/
I have since expanded that to include updates by using TG_OP to
determine the operation being done on the table.
There is also pg_audit
