Problem with pl/python procedure connecting to the internet

Hi,

I'm a beginner with pgsql and have the following problem. I have written
a pl/python procedure to query geolocations (with the library geopy). It
inserts them into a table. All this works perfectly.

The problem is the configuration with the network connections. I'm using
pgsql in a private laptop. In order to let the procedure get results
from the internet I had to put

listen_addresses = '*' (in postgresql.conf) and
host all all 0.0.0.0/0 trust (in pg_hba.conf)

I don't think this is a good solution. Moreover: it doesn't work in all
places (work, home, etc.), since I imagine it depends on the fact that
the port is open.

My question is therefore:
1. is there a way to permit the pl/python to connect to the internet all
   the time and with a better configuration?
2. or should I forget the procedure and write a python script outside
   the database?

Many thanks in advance.
