What we found is that using lz4 compression on JSONB data is 20-25% larger
on disk than pglz. We are running a production workload that is storing
jsonb data with a focus read performance. The documented increase in write
speed wasn't a large benefit, however, the increase in storage size moved

I'm rather new to the mailing list, are there any additional steps I should
take (i.e. posting to pgsql-hackers, etc.)?

No differences.
4) Was this done on same machine? If not how are the machines different?
Same AWS RDS Postgres instance.
5) How the upgrade was done?

Hello,
We are seeing an increase in the reported storage size of our jsonb columns
(using pg_column_size) since upgrading to Postgres 15.5 from version 14.
The increase in size is enough to push us over the size threshold and more
of our data to get written to the TOAST table.
I can't find any in
