Interesting. I got just today a bug report that is actually a symptom
that people should be careful about: it is possible that
pg_stat_replication reports 1/potential for sync_priority/sync_state
in the case of a WAL sender in "backup" state: a base backup just
needs to reuse the shared memory slot of a standby that was previously
connected. Commit 61c7bee of Magnus fixes the issue, just let's be
careful if there are similar reports that do not include this fix.
