isolation tests are not being run in buildfarm

Hi,

I think we're not running the isolation test suite.  I noticed that the
stage seemed to take too little time (zero seconds in fact), and looking
into the stage logs only says'make check' is not supported.Install PostgreSQL, then 'make installcheck' instead.

This should probably be fixed.

[ ... looks some more ... ]   Oh, it seems inconsistent.  Several hosts
do not run it at all; chinchilla and anchovy are running the wrong make
target; but at least chough seems to be doing it right.  Crake is good
too.

Apparently the animals (err, birds) run by a certain Andrew Dunstan are
working correctly.  I wonder why that might be.
