As far as I can tell you *are* starting the postmaster, and it is
responding when you query it via TCP (eg, with "psql -h localhost").
What is not working is connections via the Unix socket. I still
suspect that the problem there is that the postmaster is creating
the socket file somewhere other than /tmp, but your client library
thinks /tmp is where to look.
