Once the existing data is copied, the worker enters synchronization mode, which ensures that the table is brought up to a synchronized state with the main apply process by streaming any changes that happened during the initial data copy using standard logical replication. The walsender process starts logical decoding of the WAL and loads the standard logical decoding plugin. PostgreSQL 11 introduces support for Just-In-Time (JIT) compilation to Learn more about PostgreSQL and participate in our The most intuitive database upgrade way that you can think of is to generate a replica in a new version and perform a failover of the application into it, and actually it works perfectly in other engines.

In order to be able to copy the initial data, the role used for the replication connection must have the SELECT privilege on a published table. If you have a load balancer like HAProxy, you can configure it using the PostgreSQL 11 as active and the PostgreSQL 12 as backup, in this way: So, if you just shut down the old primary node in PostgreSQL 11, the backup server, in this case in PostgreSQL 12, starts to receive the traffic in a transparent way for the user/application. This method has a lot of limitations when thinking of an upgrade, as you simply cannot create a replica in a different server version or even in a different architecture. And from that moment he was decided on what his profession would be. To verify the status of replication in the primary node you can use pg_stat_replication: To verify when the initial transfer is finished you can check the PostgreSQL log on the subscriber: Or checking the srsubstate variable on pg_subscription_rel catalog.

In the new time-series database world, TimescaleDB and InfluxDB are two popular options with fundamentally different architectures. The data in serial or identity columns backed by sequences will be replicated as part of the table, but the sequence itself would still show the start value on the subscriber.
