[ shrug... ] How do you know that's a bogus prefix? It could perfectly well be a fully valid setting for an extension that the installation doesn't choose to preload.
Well, we do have ways to view all *potential* extensions. I find myself more sympathetic to the OP than the others here, as I think it's a good idea to display a warning for a potentially misspelled GUC prefix (but do nothing else - certainly not remove it!). Will such a warning be seen? Perhaps not, but that's a risk any warning message has to face. And obviously there could be false positives if an extension decides to name their GUCs something other than pg_available_extensions()->name but hopefully that's a rare case (and shame on them if so.)
