Is there any example of how to use pgsql as db core on wiki ?

I tried to adapt this example

for pgsql but no success.

I'm trying to connect to it fhru openvpn.

tcpdump -i tap1 on the destination server doesn't show any packet exchange.

I set odbc.ini as this :

[freeswitch-pgsql]
Driver   = /usr/lib64/psqlodbc.so
SERVER   = 10.0.0.1
PORT     = 5432
DATABASE = freeswitch

and set all xml conf where odbc-dsn is as this :

didn't find anything interesting on google

Thanks
