I can assure you that the Postgres backend will never do any such thing.
Your problem must be somewhere in the communication pathway.

One likely possibility is that you have an address-translating firewall
(NAT box) between you and the database server.  NAT boxes will commonly
forget about connections that have been idle for too long.  It may not
be possible to persuade the firewall not to do this --- if you cannot
bypass the firewall, your best bet may be to issue an empty query every
so often to keep the connection alive.
