Excellent, thanks. Two minor things:

* Can you supply this as a diff? Ideally as a github branch, but 
any ol' diff is fine.

* Have you tested against older versions of Postgres? I don't know 
offhand which columns from pg_stat_activity go back how far, but 
check_postgres purports to check back to version 8.
