Sharing a new extension released recently which allows Postgres to store protobuffers natively called pgproto.
https://pgxn.org/dist/pgproto/
Results: Much faster than JSONB for using Postgres as a NoSQL / SQL hybrid, uses 65% less storage space and is 37% faster to retrieve.
It also fairs pretty well against native postgres columns and joint tables.
Just wanted to see if we should add this to the page.
