Does that table have any dropped columns? If you don't remember
whether you ever dropped any columns, a quick look into pg_attribute
will tell you:
select attname from pg_attribute where attrelid = 'rma.serial_number'::regclass;
plpgsql isn't tremendously good with rowtypes that contain dropped
columns. I believe this particular case is fixed in CVS HEAD, but the
patch was a bit invasive and won't get back-ported to existing releases.
The workaround is to drop and recreate the table without any dropped
columns.
