How can I monitor the replication status in PostgreSQL?
You can monitor the replication status in PostgreSQL by querying the pg_stat_replication
view. This view provides information about the status of each replication connection.
What specific information can I get from pg_stat_replication
?
From pg_stat_replication
, you can get details like the state of the replication, the current WAL location, and the last received and replayed WAL locations.
Are there any specific commands I should run to check this?
Yes, you can run the command SELECT * FROM pg_stat_replication;
to see the current replication status.
What if I notice that the replication is lagging?
If you notice lag, you can check the pg_current_wal_lsn()
and pg_last_wal_receive_lsn()
to diagnose the issue further.
