This was discussed on -hackers a while ago: http://www.postgresql.org/message-id/flat/52EF20B2E3209443BC37736D00C3C1380876BDC7@xxxxxxxxxxxxxxxxxxxxxxxxx#52EF20B2E3209443BC37736D00C3C1380876BDC7@xxxxxxxxxxxxxxxxxxxxxxxxx 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.
