Right, so your problem is you're trying to use CURSOR, which you are leaving open on the off-chance your visitor will returns and wants to see the 'next record' or something. I think that really you just should bite the bullet and use the better syntax on SELECT. You may have a little more programming work to do, but it has little impact on performance as far as I can see. PostgreSQL will optimise queries differently when they have LIMIT clauses too.
