Well, I think we can conclude that the function is pushing way more
data into the temp table than you expect.  I am wondering if that loop
in the middle of the function is turning into an infinite loop --- could
it be finding some sort of cycle in your page data?  You might want to
add some RAISE NOTICE commands to the loop so you can track what it's
doing.
