OTOH, I was thinking of your original problem. If you could have two identical
tables, one to store incoming posts and other to store approved posts, that
should be lot more simpler.

Of course you need to vacuum much more if you are deleting from in queue but
the kind of database you are handling, me need not tell you about vacuum..

Just a though..
