Don't print extra parens around expressions in extended stats The code printing expressions for extended statistics doubled the parens, producing results like ((a+1)), which is unnecessary and not consistent with how we print expressions elsewhere.
Fixed by tweaking the code to produce just a single set of parens. Reported by Mark Dilger, fix by me. Backpatch to 14, where support for extended statistics on expressions was added.
