It shouldn't hurt correctness, but I don't think you entirely grasp the magnitude of the performance hit you'll take. The last time I tried running the regression tests with CLOBBER_CACHE_ALWAYS enabled, they took about one hundred times longer than normal. Now you are evidently hoping not to disable the caches entirely, but I don't understand how you are going to handle the various random CacheInvalidateRelcache calls that are here and there in the system (not only in btree). regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
