Пример использования логической репликации PostgreSQL max_replication_slots — максимальное количество replication slot’ов ; synchronous_commit — имеет такой же смысл для логической репликацииИспользование логической репликации. На обеих машинах создаем какие-нибудь таблицы: DROP TABLE IF EXISTS test; CREATE... postgresql - postgresql логическая репликация -… postgres=# select pg_drop_replication_slot('mysub'); ERROR: replication slot "mysub" does not exist.Поскольку вы не смогли отбросить слот репликации, неудивительно, что создание новой подписки с тем же именем (и, следовательно, слотом для репликации) терпит неудачу. Postgres 9.4, replication slots, не работает master failover… Если после проверки работоспособности слота репликации я отключаю standby, то после его включения данные с мастера подгружаются.Мастер пока не синхронизирован, содержит старые данные, репликация, понятное дело, не работает.

There is one manual step however; physical replication does not copy replication slots, so in the case of failover we need to create a slot manually PostgreSQL: Documentation: 11: 52.80. pg_replication_slots The pg_replication_slots view provides a listing of all replication slots that currently exist on the database cluster, along with their current state.

Failover slots for PostgreSQL - 2ndQuadrant A physical failover slot can be created, just like a logical failover slot. Does this mean pglogical can be used to fail over to a logical replica? Failover slots do not aid logical replication solutions in supporting failover to a logical replica. They exist to allow logical replication to follow a physical failover. Replication in MySQL vs. PostgreSQL - covermymeds.com BDR is still pretty new territory and we have elected not to run it in our environment yet. It looks like it will help to address some of the “all or nothing” issues that currently exist in Streaming Replication. High Availability. MySQL gives you the power to do whatever you want. Monitoring replication peers - Postgres-BDR | 2ndQuadrant 7.3. Monitoring replication peers. As outlined in Why monitoring matters it is important to monitor the state of peer nodes in a BDR group. There are two main views used for this: pg_stat_replication to monitor for actively replicating nodes, and pg_replication_slots to monitor for replication slot progress.
