This is to be expected. Connection via telnet to the DB is not supported ;-)
What the LOG entry tells you, though, is that the database is waiting for 
network connections, so your setup should be OK.
Please try with psql: 'psql -h localhost -U <your username> template1'
You should either get an errormessage, or a login prompt.
