I can't speak to the technical difficulties, but *I* would use it. Note that on the backend Postgres is still going to re-write the entire JSON value. Also, we'd want both a json_patch and jsonb_patch, which would have the same syntax but different internal plumbing. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
