We did a little more digging on our side, which I apologize for not
doing beforehand.
We wrote a script to create a simple table with a jsonb column, inserted
some json data into the column and then used *pg_column_size* to test
the size of the jsonb data column.
We ran the script against local docker versions of postgres 14.8 and
15.5 and saw that the data in the jsonb column was the same size.
We then ran the script on AWS RDS Postgres and saw a size difference for
the same json data between versions 14.8 and 15.4 (we also saw the
larger size on RDS postgres 15.5 and 16.1).
This points at RDS Postgres being the issue. Since that is behind the
AWS curtain, you will need to contact AWS technical support for
information on what changed.
*Version* *size (kb)* *notes *
RDS Postgres-14.8 1587 (the same size we were seeing locally)
RDS Postgres-15.4 2112
Thank you for your prompt responses and assistance.
If you are curious, I can share the script we used with you.
Kind regards,
Sean
