pgsql: Update ecpg's connect-test1 for connection-failure message chang

Update ecpg's connect-test1 for connection-failure message changes.

I should have updated this in commits 52a10224e and follow-ons,
but I missed it because it's not run by default, and none of the
buildfarm runs it either.  Maybe we should try to improve that
situation.
