This patch changes the existing 'conflicting' field to 'conflict_reason' in pg_replication_slots. This new field indicates the reason for the logical slot's conflict with recovery. It is always NULL for physical slots, as well as for logical slots which are not invalidated. The non-NULL values indicate that the slot is marked as invalidated. Possible values are: wal_removed = required WAL has been removed. rows_removed = required rows have been removed. wal_level_insufficient = the primary doesn't have a wal_level sufficient to perform logical decoding. The existing users of 'conflicting' column can get the same answer by using 'conflict_reason' IS NOT NULL.
