Обсуждение: pgsql: Remove outdated join_1.out regression test comparison file.

Log Message:
-----------
Remove outdated join_1.out regression test comparison file.  This has
been broken for more than a month, so evidently it's not needed, at
least not for any configuration in the buildfarm.  We can correct it
and replace it later if we find something that still needs it.
