My router is simply an ADSL modem, I have no control over the
multitude of routers that are in the way between my house and
rackspace or linode. My router is probably not that tunable but I'll
take a look.
I should mention that none of my ssh sessions suffer from the same
issues. I can have an ssh session open for days if I want.
As an aside...
Why does losing the connection lock up the entire application? That's
the annoying bit, having to launch another instance of pgadmin because
the first one completely unusable and establishing a second
connection.
