Maybe.  After thinking a bit more, I seem to recall one of the reasons
for having wide parallel sets in the regression tests is that we
*wanted* to consider inability to support a dozen or two connections as
a serious problem.  If we still believe that old logic, then indeed the
right thing to do is for initdb to insist on setting max_connections no
smaller than 20.  (Pre-7.4, the default setting was generally 32, so
this is still more flexible than before from a portability standpoint.)
