Frankly I don't remember all details since I did this benchmark in February. IIRC its "ZSON + PGLZ" vs "JSONB + PGLZ".

Please note that everything depends very much on your data. PostgreSQL is smart about what to compress and what not. In general it could be all combinations of "ZSON +/- PGLZ" vs "JSONB +/- PGLZ".

Don't believe any benchmark I or anyone else did. Re-check everything on your data, configuration, hardware, workload, etc.
