Vadim Zeitlin 605db30f6c Reuse correct connection parameters for PostgreSQL failover ...

If the failover callback doesn't provide the connection string to use,
default to the originally used one instead of using empty connection
string which is almost certainly not what we want.

Note that this requires storing the original connection parameters in
postgresql_session_backend, as we don't have access to the ones stored
in the session object and it seems wrong to add backlinks from the
backend to the session object.

Closes #793.
