Best Way to handle duplicate key exceptions

["Peter Neu" <peter(dot)neu(at)gmx(dot)net>]

Hello,

what is he best way to handle duplicate key exceptions? When I do bulk
import I don't want
the insert process to fail simply because somebody gave me an inconsistent
csv file.

Is there simple way to tell Postgres to simply insert everything that is
good and let me log the errors?

Cheers,
Pete
