I may be suffering from some form of the Mandela Effect but I have a
distinct memory that once upon a time SHOW actually took patterns like
\d does. I keep trying it, forgetting that it doesn't actually work.
I'm guessing my brain is generalizing and assuming SHOW fits into the
same pattern as \d commands and just keeps doing it even after I've
learned repeatedly that it doesn't work.
Personally I would like to just make the world match the way my brain
thinks it is and make this just work:
SHOW enable_*
I don't see any value in allowing * or ? in GUC names so I don't even
see a downside to this. It would be way easier to discover than
another \ command
