invalid-page hash table, PANIC immediately. Immediate PANIC is much better than waiting for end-of-recovery, which is what we did before, because the end-of-recovery might not come until months later if this is a standby server. Also refrain from creating a restartpoint if there are invalid-page entries in the hash table. Restarting recovery from such a restartpoint would not see the invalid references, and wouldn't be able to cross-check them when consistency is reached. That wouldn't matter when things are going smoothly, but the more sanity checks you have the better. Fujii Masao
