Hmm.  I do not think so.  The worrisome possibility is that our earlier
changes that make the postmaster fork() first and authenticate later
might be hurting performance, rather than helping it, at least on
Windows.  But it's difficult to see why.  Successful connections must
do a fork() sooner or later, so how could there be any net loss of

What authentication protocol are you using in this test?

Quite a few of the tests are dependent on data inserted by earlier
tests, so I wouldn't worry too much about failures occurring after the
first connection-refused.  You could look at the detail diffs and verify
that they look like missing data or missing tables.

I doubt it.
