Re: Multiple hosts in connection string failed to failover in non-hot standby mode

It seems like nobody's terribly interested in figuring out why
pg_GSS_have_cred_cache() is misbehaving on Windows.  So I took
a look at disabling GSSENC in these test cases to try to silence
hamerkop's test failure that way.  Here's a proposed patch.
It relies on setenv() being available, but I think that's fine
because we link the ECPG test programs with libpgport.

            regards, tom lane
