I believe the issue is that those BF members have kernel settings that
only support running one postmaster at a time.  The way you've got this
set up, it launches a new private postmaster during a make installcheck;
which is not only problematic from a resource consumption standpoint,
but seems to me to violate the spirit of make installcheck, because
what it's testing is not the installed postmaster but a local instance.

Can you confine the test to only occur in "make check" mode, not "make
installcheck", please?

                        


Contrib tests are only run by the buildfarm in installcheck mode, so that will probably turn the tests off for the buildfarm, so +1 on that :-) I think these tests are probably somewhat ill-conceived. Note also that shell scripts are not portable, and so these tests would not be able to run on MSVC buildfarm members, even if they had been enabled in the MSVC regression driver, which they have not. If we need a regression driver script it needs to be written in Perl.

Also note that the test as written is likely to add significantly to buildfarm run times, as it will run the entire base regression suite again, possibly several times.

Finally, I think that this is probably not what we really need. I have already started work (as I mentioned some weeks ago) on having the buildfarm stash away a successful build and data directory, to be used later in cross-version upgrade testing, which seems to me much more what we need from something like the buildfarm. Maybe we could discuss how to run something like that.

And yes, some buildfarm members run on fairly scarce machine resources, of memory, CPU time and disk space, and we need not to increase what our tests use without due notice and care.
