Theworst thing about those, is you can't even force kill those connections from within postgres (pg_cancel_backend
doesn'twork on them, and killing them via the OS bounces postgres ...) so you have to hunt down the offending client.

Ooh, I just noticed pg_terminate_backend() ... maybe this will let me kill annoying idle in transaction clients.  I
guessthis arrived in 8.4?  Hopefully this won't cause the whole thing to bounce and close all other backends....
