Right, 'Idle in transaction'.  Agree that a setting directed purely at
that problem could set a much lower timeout, say, 5 minutes or less
since it almost never comes up in real applications.  In fact, in 15
years of postgres development, I've never seen 'idle transaction' that
indicated anything but application malfunction.

I can +1 that.

That being said, hour timeout for general case would work for me.  It
would only have to be set lower for very busy OLTP databases where
continuous vacuum is essential.   In those cases, I don't mind forcing
all batch processes to disclose in advance they are running long.

Yeah about an hour sounds right.
