listening on tcp socket instead of unix domain

Hoping to get postgresql to listen on a tcp socket I made the
following change to postgresql.conf:

#listen_addresses = 'localhost' # what IP interface(s) to listen on;
listen_addresses = 'localhost' # what IP interface(s) to listen on;
# defaults to localhost, '*' = any
#port = 5432
port = 5432

I understand this to mean, listen on localhost, ie 127.0.0.1.

However, a netstat -l tells me:

netstat -l | grep 5432
unix 2 [ ACC ] STREAM LISTENING 732094 /tmp/.s.PGSQL.5432

netstat -l | grep postg
tcp 0 0 localhost:postgresql *:* LISTEN
tcp 0 0 localhost:postgresql *:* LISTEN

This doesn't look right. Moreover, when attempting to create an ssh
tunnel to connect to postgres from a windows box, the connection
fails.

Is postgres really listening on a socket that is 'connect-able'
through ssh tunneling? If so, then would using ssh command

ssh -L 5432:remotehost:5432 user(at)remotehost

be sufficient to connect to the postgres running on remote host? This
fails when running psql on the machine with message:

> psql -p 5432
psql: could not connect to server: No such file or directory
...

So, I don't think something is quite working. Please advise.
