1. Stop a running sequence synchronization worker when ALTER SUBSCRIPTION ... DISABLE is executed. The worker did not reread its subscription after starting a transaction, so it kept running with a stale copy and missed the disable. It now calls maybe_reread_subscription() after StartTransactionCommand(), matching the apply worker. 2. Restore the invariant that publisher-side synchronization slots are dropped last during ALTER SUBSCRIPTION ... REFRESH PUBLICATION. The slot-drop loop now runs after the sequence-removal loop, so the non-transactional slot drops happen only after all catalog changes that could still be rolled back on error. 3. Restore psql tab completion for ALTER SUBSCRIPTION ... REFRESH PUBLICATION WITH (. 4. Make pg_stat_subscription report NULL for the fields that do not apply to a sequence synchronization worker, which does not stream from a walsender, and update the documentation accordingly. 5. Update the pg_subscription_rel.srsublsn catalog documentation to describe its semantics for sequence rows.
