Works for me in 8.4.11 (after correcting record_var.id -> record_var.pid
at line 6).  Maybe you need to update to some more recent version than
8.4.0.

Actually, I do get the described behavior when trying this in 8.3,
which does not have FOR-over-cursor.  So maybe the more appropriate
question is whether you're really running 8.4.anything.

Hi Tom,
=20
Well I thought I was running version "8.4.*" but it turned out to be "8.2.1=
4" when I did a show server_version in pgAdminIII. So, is this a known issu=
e?=20
Well I won't possibly be able to upgrade the version as its bundled with th=
e DB. :-(
