Multiple simultaneous queries on single connection

Hello list,

We want to access a postgres database with multiple queries / result
sets that are read simultaneously (hence async). The documentation says
explicitly that no new PQsendQuery can be send on the same channel
before the pqgetresults has returned null. This means we need to use
multiple connections.

The problem is that multiple connections (from the same application
instance) do not share the same MVCC snapshot.

Is there a way to have two or more connections see each others
uncommitted things?

Any thoughts?
