SP-GiST initialized an all-zeros page at vacuum, but that was not WAL-logged, which is not safe. You might get a torn page write, when it gets flushed to disk, and end-up with a half-initialized index page. To fix, leave it in the all-zeros state, and add it to the FSM. It will be initialized when reused. Also don't set the page-deleted flag when recycling an empty page. That was also not WAL-logged, and a torn write of that would cause the page to have an invalid checksum. Backpatch to 9.2, where SP-GiST indexes were added. |
