Обсуждение: audit trigger (update)

Hallo,

on
http://wiki.postgresql.org/wiki/Audit_trigger

the 
RETURN NULL 
in the delete part of the trigger
should be
RETURN OLD

about the other RETURN NULL,
one can discuss.

mvg,
Wim Bertels

yes it does,
otherwise this audit_trigger cancels delete statements
(as it is processed before in this example)
