Re: Database port changing issue

That's because your listen_addresses parameter points to localhost,
and that means that your will listen for connections through unix
sockets instead of via TCP/IP.

In order to change this, you'll need to replace the string localhost
with the proper value. (A bad habit, to replace the 'localhost' with a
'*').

Read the man page :)

# - Connection Settings -
listen_addresses = 'localhost' # what IP address(es) to listen on;

# Would be something like:
listen_addresses = '*'

Best wishes,
Guido
