pgsql: Fix errors in copyfuncs/equalfuncs support for JSON node types. - Mailing list pgsql-committers

Fix errors in copyfuncs/equalfuncs support for JSON node types.

Noted while comparing existing code to the output of the proposed
patch to automate creation of these functions.  Some of the changes
are just cosmetic, but others represent real bugs.  I've not
attempted to analyze the user-visible impact.

Back-patch to v15 where this code came in.
