So I was using their guide for minimal downtime upgrades [0], see option 'D'. And I was replicating Pg 11 to 14. Logical replication appeared to work in that case yet big tables would never catch up or appear to get truncated. If you're replicating among nodes at the same Pg version then built-in replication may work for you. Once I switched to pglogical jumping major versions worked as intended. Now it's possible in the rush I used the wrong setting somewhere and built-in logical replication can work between major versions. Though I lost enough time experimenting I'll keep using pglogical until AWS officially recommends something else.
