While rearranging code in tidpath.c, I overlooked the fact that we ought to check restriction_is_securely_promotable when trying to use a join clause as a TID qual. Since tideq itself is leakproof, this wouldn't really allow any interesting leak AFAICT, but it still seems like we had better check it. For consistency with the corresponding logic in indxpath.c, also check rinfo->pseudoconstant. I'm not sure right now that it's possible for that to be set in a join clause, but if it were, a match couldn't be made anyway. |
