[HACKERS] JSON Patch (RFC 6902) support?
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? https://tools.ietf.org/html/rfc6902 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 such as: // applies a JSON Patch json_patch_apply(json, patch) // diffs two JSON objects and produces a JSON Patch json_patch_diff(json a, json b) Thanks, Ryan Pedela

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

But without committing myself I'll be interested to see a patch. cheers andrew -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
