A big +1 on this refactoring.

Was the source pgindented, but not committed, before generating the patches? I
fail to apply them on master (or REL_12_STABLE) on what seems to be only
whitespace changes.

Having read the patch I agree that it's trivial enough that I wouldn't be
worried to let it slip through. However, given that we've lacked the check for
a few releases, is it worth rushing with the potential for a last-minute
"oh-shit"?

No need to check typlen?
