You can always create a bot for this sort of thing...using AutoWikiBrowser it shouldn't take more than a few minutes (if your account has bot status) depending on the size of your wiki. There's also this script which doesn't require you to download anything.

However, are you aware of Special:Allpages? This lists all the pages on the wiki so a category really isn't necessary. :)
