Dear Colleagues,
When upgrading to a new major version, pg_upgrade documentation
https://www.postgresql.org/docs/current/pgupgrade.html#PGUPGRADE-STEP-REPLICAS
states that pg_upgrade can be used on a master server. After upgrading
the PostgreSQL version on standbys, however, one must either pull the
data from scratch with pg_basebackup, or run rsync from master to
standby.
Is running pg_upgrade on replicas not supported and why?
