Re: PostgreSQL logical replication depends on WAL segments?

[Jeremy Finzel <finzelj@xxxxxxxxx>]

Note replication slots only prevent old *catalog* rows from being
removed, not old row versions in user created tables.

Thank you for that clarification.  I can see this is noted clearly in the CAUTION statement here: https://www.postgresql.org/docs/current/logicaldecoding-explanation.html#LOGICALDECODING-REPLICATION-SLOTS

Thanks,

Jeremy
