The problem is PostGresPostgres is binding to your loopback address (127.0.0.1). This typically means that your database will not accept connections outside your loopback. It is evident based on your results running netstat.
The Solution:
You need to modify your pg_hba.conf file to allow outside connections (preferrably, your PC's IP address). Take a look at the following. I'm not 100% what version of Postgres your using but I can't imagine each version having vast differences between configuring your pg_hba.conf.
