There is no disconnect timeout in Postgres.
This sort of thing has been reported before, and it's always been due to
overaggressive dropping of idle connections by a firewall in between the
clients and server. NAT routers have to keep per-connection state about
the address mapping, and they will drop that state after some period of
no traffic. 10 minutes seems unreasonably short though. I hope it's
configurable on your box. If not, you can either buy a more reasonably
designed router, or tweak your clients so they do something at least
once every few minutes...
