Add more SQL/JSON constructor functions
This Patch introduces three SQL standard JSON functions:
JSON()
JSON_SCALAR()
JSON_SERIALIZE()
JSON() produces json values from text, bytea, json or jsonb values,
and has facilitites for handling duplicate keys.
JSON_SCALAR() produces a json value from any scalar sql value,
including json and jsonb.
JSON_SERIALIZE() produces text or bytea from input which containis
or represents json or jsonb;
For the most part these functions don't add any significant new
capabilities, but they will be of use to users wanting standard
compliant JSON handling.
Catversion bumped as this changes ruleutils.c.
