The original coding was quite sloppy about handling the case where XLogReadBuffer fails (because the page has since been deleted). This would result in either "bad buffer id: 0" or an Assert failure during replay, if indeed the page were no longer there. In a couple of places it also neglected to check whether the change had already been applied, which would probably result in corrupted index contents. I believe that bug #5703 is an instance of the first problem. These issues could show up without replication, but only if you were unfortunate enough to crash between modification of a GIN index and the next checkpoint. Back-patch to 8.2, which is as far back as GIN has WAL support. |
