After re-reading the description of pg_get_keywords, I was reminded that
what it outputs now is intended to provide both a machine-friendly
description of the keyword category ("catcode") and a human-friendly
description ("catdesc"). So we really should do likewise for the
label property. What I now propose is to add two output columns:
barelabel bool (t or f, obviously)
baredesc text ("can be bare label" or "requires AS", possibly localized)
Feel free to bikeshed on those details.
