First: Please don't full quote emails.
Secondly: You've not actually explained what you want to do, nor what
your precise question itself is. Nor why Michael or my answer wasn't
sufficient.

Logicla decoding looks at the catalogs for metadata - otherwise the WAL
would need to contain a lot more information and thus be more voluminous
- so the records do *not* contain the "full information".

Please start at the beginning and explain what you're trying to do
(since you apparently did some hacking to get a slot on a standby) and
what you're trying to achieve, instead of one-sentence questions.
