Can you clarify what you want to see here?  You can see the current and last queries of connections with "SELECT * FROM pg_stat_activity".  If you want auditing or logging of all activity then depending on what you need it's possible with triggers or an extension like pg_audit.

Yes turn on log_connections and log_disconnections, see the "what to log" section here:
