I am interested in adding Protocol Buffer support for Postgres.
Protocol Buffer occupies less space than JSON. More importantly, it
has schema and is forward/backward compatible. All these make it a
very good format for persistency.
Have you investigated JSONB vs ProtoBuf space usage ?
(the key being the "B" -- Postgres' own binary JSON implementation)
The "per-column schema" thing sounds difficult to do without major
changes to the core unless/until we have generalized user-defined
metadata for objects ....
