This is my first email to the PostgreSQL mailing lists so I hope this is
the correct place. If not, please let me know.
I was wondering if it would be possible and wise to support JSON Patch?
One of the problems I have as a user is how to update a portion of a JSON
object efficiently. Right now I have to read the entire field from the
database, update it, and then write it back. I am thinking JSON Patch might
be a good way to solve this problem because it would allow partial updates
and I think it could easily fit into the existing set of JSON functions
// applies a JSON Patch
// diffs two JSON objects and produces a JSON Patch
json_patch_diff(json a, json b)
