Replication in PostgreSQL uses streaming as a strategy to achieve high availability (HA). This guide covers how to set up PostgreSQL streaming replication.
PostgreSQL has some building blocks for replication monitoring, and the following are some important functions and views which can be use for monitoring the replication: 1. pg_stat_replication view on master/primary server. This view helps in monitoring the standby on Master. It gives you the fo...
Once physical streaming replication has been set up and configured in PostgreSQL, failover can take place if the primary server for the database fails. Failover is the term to describe the recovery process, which in PostgreSQL,can take some time, particularly as PostgreSQL itself does not provid...
Tablespace replication conflicts:A tablespace is intemp_tablespaceson the standby server, and a query has temporary files there. When aDROP TABLESPACEoccurs from the primary, we get a conflict. PostgreSQL cancels all queries on the standby in that case. ...
Streaming replication is a core utility of PostgreSQL introduced in version 9.0. Streaming replication allows a standby server to stay more up-to-date than is possible with file-based log shipping.
Typically, data replication in PostgreSQL is done between an active (primary) database and one or more standby databases. While this is usually enough for ma...

You need to manually update the sequence value in the destination database. For details, see Forcibly Stopping Synchronization of PostgreSQL. To forcibly stop a full+incremental real-time synchronization task, you need to manually delete the replication slots that may remain in the source database....
