Why should logical replication break?
LR gets fiddly, and needs manual attention when DDL changes are applied, no?
For example, we're not using LR to migrate from 9.6 to 14 because the application regularly makes DDL modifications (inheritance partitioning: dropping old tables, creating new ones, and dropping/recreating the triggers; 71 of them). I don't trust my ability to catch all those changes, and apply them to the new server.
Why would you want to fill your repl slots (if any) by suspending physical replication while pg_repack runs?
