Complete the following TODO items:
* Add session start time to pg_stat_activity * Add the client IP address and port to pg_stat_activity Original patch from Magnus Hagander, code review by Neil Conway. Catalog version bumped. This patch sends the client IP address and port number in every statistics message; that's not ideal, but will be fixed up shortly.
