The thing which comes most close to a rejection was the 'I can't decide' mail
by you (answered by Tom). The conclusion sounded like 'since we're not clear on
this subject we won't touch this, yet'. And there was some unsettled discussion
about the best wording to show in 'ps'.
'trans' seemed too short (and too much unlike 'idle') (as indicated by Bruce)
and 'idle (open transaction)' might give difficulties on platforms which limit
the length of the string (as indicated by Tom)
I'll CC Hackers (where this discussion belongs)

The idea seemed good to me, although I didn't look at the code to see
if the implementation was any good ;-). I know we've frequently had
questions on the lists where it was interesting to know if any
transactions were being held open --- and right now there's no easy
way to tell.

If you are looking for programs which tend to hold longstanding
transactions, this micro patch might be handy.
Whether it is of general use is debatable. It will replace 'idle' by
'trans' if the backend is idle but a transaction is pending.
Simply use ps to view the backend's status.
