Avoid row-processing-order dependency in postgres_fdw regression test.

tglsfdc · tglsfdc · commit 0247d43dd9c4 · 2013-03-12T10:47:04.000-04:00
A test intended to provoke an error on the remote side was coded in such
a way that multiple rows should be updated, so the output would vary
depending on which one was processed first.  Per buildfarm.
