Making a Persistent Postgres Connection

Hi everybody

I really would apreciate if somebody could help me on
how to make a persistent connection to a Remote
Database using "C Language". I work in "Linux"
Operating System and use the header <pgsql/libpq-fe.h>

I have any problems when I make a connection to the
Local Database, but every time I make a postgres
connection (via Internet) to a Remote Database, I find
the problem that the connections falls down every 10
minutes more or less.

I hope someone to help me to solve this, please.

My best regards.
