About the patch, IIUC earlier all the idle time was accumulated in the
"pgStatTransactionIdleTime" counter, now with your patch you have
introduced one more counter which specifically tracks the
STATE_IDLEINTRANSACTION state. But my concern is that the
STATE_IDLEINTRANSACTION_ABORTED is still computed under STATE_IDLE and
that looks odd to me. Either STATE_IDLEINTRANSACTION_ABORTED should
be accumulated in the "pgStatTransactionIdleInTxnTime" counter or
there should be a separate counter for that. But after your patch we
can not accumulate this in the "pgStatTransactionIdleTime" counter.
