Yeah, REINDEX relies on some existing index definition, so it feels
like we are missing a piece related to invalid indexes in all that. A
main difference is the lock level, as exclusive locks are getting
logged so the standby can react and wait on that. The 30-minute mark
is interesting. Ben, did you change any replication-related GUCs that
could influence that? Say, wal_receiver_timeout, hot_standby_feedback
or max_standby_streaming_delay?
