Can't tell from that much info. The postmaster's log output might tell
more about why it's refusing the connection. Right now you are sending
that log to the bit bucket, however :-(. Restart the postmaster
*without* -S, and with output redirection, eg
postmaster -i -p 5432 ... >/path/to/handy/logfile 2>&1 &
and then see what it puts in the logfile when you try to connect.

BTW, you do not need to restart the postmaster after changing
pg_hba.conf.
