This was discussed on -hackers a while ago: http://www.postgresql.org/message-id/flat/52ef20b2e3209443bc37736d00c3c1380876b...@exadv1.host.magwien.gv.at#52ef20b2e3209443bc37736d00c3c1380876b...@exadv1.host.magwien.gv.at It's a rather long and rambling thread, but what I got from it was that "=" for assignments is something that just works by accident, is discouraged and left alive only to avoid breaking code that uses it.
