Then you don't really want per-connection state, you want per-client-session
state. Presumably you're generating a unique identifier for each client
session somewhere in the client app? You could use that unique identifier
to store whatever information you need for that session in a table.

This sounds like a pretty normal "keep state based on a cookie" problem,
as solved by a bunch of web apps. If you're looking for higher performance
you might want to look at memcached and the postgresql interface to it
(pgmemcache?).
