Another case attached. see the attached SQL file's comments.
a single simple jsonb, with 33 keys, each key's value with fixed length: 256.
total table size: SELECT pg_size_pretty(pg_table_size('json33keys'));  --5369 MB
number of rows: 600001.

using the previously mentioned method: pg_log_backend_memory_contexts.
all these tests under:
-Dcassert=true \
-Db_coverage=true \
-Dbuildtype=debug \

I hope someone will tell me if the test method is correct or not.
