Re: plpgsql problem

My guess is that since userid and userID differ only in
case, it's probably not actually using the aliased version
and instead is using only the column one.

The execute is different since you're effectively putting
the *value* of userID into the query as opposed to the word.
I'd suggest renaiming the alias and seeing if that works.
