One trivial comment: + logical replication slots</link>. The system automatically increases the + effective WAL level to <literal>logical</literal> when creating the first + logical replication slot, and decreases it back to <literal>replica</literal> + when dropping the last logical replication slot. The current effective WAL + level can be monitored through <xref linkend="guc-effective-wal-level"/> + parameter.
Shouldn't we mention about invalidation of slot along with dropping of slot? thanks Shveta
