Umm.. out of box, I don't think so. May be some triggers etc. can be placed
for information..Can you describe what you are trying to achieve?

You need priorities to connections or transactions?

Yes. See pgpool(http://pgfoundry.org/projects/pgpool/)

No. PostgreSQL backend process is single threaded. However each connection
gets a separate backend process. Hence on SMP machines, all available CPUs
can potentially be used for multiple connections.
