Re: Cancel/Kill backend functions

Okay, here is an updated patch. now uses IsBackendPid(), which is
closely modeled (read cut-and-pasted) from TransactionIdIsInProgress().

Since it's no longer a pgstat function, I moved it to "misc.c". Not 100%
that's the right place either, but it seemed like the best alternative.
