when we are waiting for old snapshots to go away during a concurrent index build. In particular, this rule lets us avoid waiting for idle-in-transaction sessions. This logic could be improved further if we had some way to wake up when the session we are currently waiting for goes idle-in-transaction. However that would be a significantly more complex/invasive patch, so it'll have to wait for some other day. Simon Riggs, with some improvements by Tom.
