Your SQL does not do what you think it does.

You should probably test your SQL at the psql command line to figure out
the correct way to do what you want to do before you try and post to a
PHP mailing list about this kind of thing.

I'd offer advice, but I can't figure out from your statement what you're
trying to do your database either.
