The MSVC members of the buildfarm seem to not like my recent patch
b14cf229f4bd7238, which basically did this to contrib/hstore_plpython's
Makefile:

  SHLIB_LINK += ../hstore/libhstore.a $(wildcard 
../../src/pl/plpython/libpython*.a) $(wildcard 
../../src/pl/plpython/libplpython*.a)
  endif
-REGRESS_OPTS = --load-extension=hstore
+REGRESS_OPTS += --load-extension=hstore
  ifeq ($(python_majorversion),2)
  REGRESS_OPTS += --load-extension=plpythonu --load-extension=hstore_plpythonu
  endif

Now they're failing to load hstore before running the regression test, eg
http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=bowerbird&dt=2015-05-18%2015%3A37%3A17

Looking at vcregress.pl's sub fetchRegressOpts, it seems that it only
notices "REGRESS_OPTS =" lines not "REGRESS_OPTS +=" lines, so that
isn't surprising --- but how is it that the tests *are* still loading
plpythonu and hstore_plpythonu?  I grant that my Perl is weak, but
I don't see how this code would ever have dealt with either lines
using +=, or multiple assignments to REGRESS_OPTS.  How come it worked
before?


relevant code:

    if ($module eq "hstore_plpython" ||
        $module eq "ltree_plpython")
    {
        die "Python not enabled in configuration"
            if !defined($config->{python});

        # Attempt to get python version and location.
        # Assume python.exe in specified dir.
        my $pythonprog = "import sys;" .
          "print(str(sys.version_info[0]))";
        my $prefixcmd = $config->{python}
              . "\\python -c \"$pythonprog\"";
        my $pyver = `$prefixcmd`;
        die "Could not query for python version!\n" if $?;
        chomp($pyver);
        if ($pyver eq "2")
        {
            push @opts, "--load-extension=plpythonu";
            push @opts, '--load-extension=' . $module . 'u';
        }
        else
        {
            # disable tests on python3 for now.
            chdir "..";
            return;
        }
    }
