Dear, I have a query to make you As much as you enable hot_standby_feedback = on, queries continue to be canceled, in addition to enabling this parameter you have to modify any of these? #max_standby_archive_delay = 30s #max_standby_streaming_delay = 30s #wal_receiver_status_interval = 10s The idea that we have is to have a primary, a standby for high availability and a second standby database in cascade from the replica to be able to execute reports and not interfere with the other two databases -- Sent from: http://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
