BTW, it looks like the Windows buildfarm critters have a
separate problem: they're failing with

initdb: error: must specify a password for the superuser to enable md5 authentication

One would imagine that even if we'd given a password to initdb,
subsequent connection attempts would fail for lack of a password.
There might not be any practical fix except forcing trust auth
for the Windows critters.
