Yeah, a GUC check hook that tries to inspect the value of some other GUC is generally going to create more problems than it solves; we've learned that the hard way in the past. We have your patch to remove one instance of that on the CF queue: https://www.postgresql.org/message-id/flat/ZnMr2k-Nk5vj7T7H@nathan But that fix only works because those GUCs are PGC_POSTMASTER and so we can perform a consistency check on them after GUC setup. I'm not sure what a more general consistency check mechanism would look like, but it would have to act at some other point than the check_hooks do. regards, tom lane
