How did you start the postmaster?
It looks like you might have the postmaster's stderr pointed at your
terminal, which would mean that its attempts to write to a logfile
will end up on your screen --- along with the message sent back to
the client and printed by psql.
You should redirect the postmaster's stdout and stderr to someplace,
either a logfile or /dev/null. See the Administrator's Guide section
about how to start the postmaster.
