Finally got around to doing this... The link below points to a complete implementation of JSONPatch in pure PostgreSQL. It is compatible with PostgreSQL >= 9.5 (Not tested using earlier versions)
Cheers!

pl/pgsql) implementation that wraps the existing json APIs to get the
desired result. From there, could determine if a more optimized
