node starts from the same place as the first scan did. This avoids surprising behavior of scrollable and WITH HOLD cursors, as seen in Mark Kirkwood's bug report of yesterday. It's not entirely clear whether a rescan should be forced to drop out of the syncscan mode, but for the moment I left the code behaving the same on that point. Any change there would only be a performance and not a correctness issue, anyway. Back-patch to 8.3, since the unstable behavior was created by the syncscan patch. |
