A short explanation of the mechanism is at the end of
src/test/regress/README.  Depending on how you invoke the regression test
you'll have to look into pg_regress,, or for the
implementation.  I recommend using 'gmake check' or 'gmake installcheck',
which would invoke the former.  The others are obsolescent.

Generally, test and set should be a lot faster.  Specifically, the non-TAS
code is probably broken and will be removed sometime.
