This blog shall help you replicating the data between PostgreSQL to PostgreSQL and PostgreSQL to Oracle databases. It would also mention how to setup the bi-directional replication for GoldenGate PostgreSQL and how to configure the GoldenGate for PostgreSQL and the Database in detail. What Do You...
--slot=SLOTNAME #optional -R = Write configuration parameters for replication #primary_conninfo will automatically be defined by the pg_basebackup command. Verify the same in postgresql.auto.conf In case of PostgreSQL version 12 and above, create a blank standby.signal file in data dir...

PostgreSQLdatabase supports several replication solutions to build high-availability, scalable, fault-tolerant applications, one of which isWrite-Ahead Log(WAL) Shipping. This solution allows for a standby server to be implemented using file-based log shipping or streaming replication, or where possible...

To:pgsql-admin@postgresql.org Subject:Re: PG how to stop streaming replication( master host) Thank you Scott, this will only pause the WAL's . if you have a lot of activity happening in master while slave db is been backup this can fail behind a lot and eventually can fill up /wal...
Deadlock replication conflicts:A query on the standby blocks while using the shared buffer that is needed to replayWALfrom the primary. PostgreSQL will cancel such a query immediately. Tablespace replication conflicts:A tablespace is intemp_tablespaceson the standby server, and a query has temporary...
PostgreSQLbuilt-in streaming replication is what is called physical: it will replicate the changes on a byte-by-byte level, creating an identical copy of the database in another server. This method has a lot of limitations when thinking of an upgrade, as you simply cannot create a replica ...
max_replication_slots and max_wal_senders must be at least 1 or higher if your server may be using more replication connections. Then your Postgres server needs to be restarted to apply the changes. I’m using an Azure Database for PostgreSQL server. In ...
for several minutes. Since node 4 stopped replication we figured that node 6 now needs to finally demote but it did not happen. So we restarted node 6 to see if it solves the issue but we ultimately ended up in the above final state. In this state node 6 did not continue anymore beca...
