Values not being updated.

[Maximiliano Pin <mcpin(at)emtesistemas(dot)com>]

We found this bug: after some weeks using a database, updates to some
table values from pgadmin are always ignored. They're aparently updated
without error, but closing the window and opening the table again shows
the value has not been changed. Adding OIDs to that table, sometimes
fixes the problem, sometimes not. Then, we must use command line psql to
update values.

Using pgadmin III 1.6.2 (Windows 2000) with postgres 8.1.2 (HP-UX).

Thanks.
