How do I set up streaming replication in PostgreSQL?
To set up streaming replication in PostgreSQL, you'll need to configure a primary and a standby server. First, ensure both servers are running the same version of PostgreSQL.
What configuration changes do I need to make on the primary server?
On the primary server, you need to edit the postgresql.conf
file to set wal_level
to replica
, and configure max_wal_senders
to allow connections from standby servers.
And what about the standby server?
On the standby server, you'll need to create a recovery.conf
file that specifies the connection details to the primary server, including primary_conninfo
.
Is there a way to monitor the replication status?
Yes, you can use the pg_stat_replication
view on the primary server to monitor the status of the replication and check for any issues.
