Hi jeff,
I'm not sure but may be that's because you are using select distinct and so
there would be a few rows with same "gid" but different "created" fields in
your table . And PG does not know which one to select and compare for ORDER
BY clause. If that ,you would need to change the table structure to a better
normal form.
