Обсуждение: pg_ctl promote
Hi, I have recently tried pg_ctl promote to promote one of our standby server to promote as primary server. Eventually I will be doing this in production. I could successfully execute the pg_ctl promote command. My only question do I have to change postgresql.conf and pg_hba.conf files manually to have parameters/settings specificto read/write server. For example: hot_standby to off from on in postgresql.conf host replication all (remove this from pg_hba.conf) Thanks. -- View this message in context: http://postgresql.1045698.n5.nabble.com/pg-ctl-promote-tp5787858.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com.

Hi,
I have recently tried pg_ctl promote to promote one of our standby server to
promote as primary server.
Eventually I will be doing this in production.
I could successfully execute the pg_ctl promote command. My only question do
I have to change postgresql.conf and pg_hba.conf files manually to have
parameters/settings specificto read/write server.
For example:
hot_standby to off from on in postgresql.conf
host replication all (remove this from pg_hba.conf)
Thanks.

To make changes to your subscription:

If you will promote your replica to master (open read/write mode) , you will not need to change the hot_standby parameter in postgresql.conf , because it will not affect the database with primary role.
The rule "host replication all" influces only who could connect to your new primary to create a hot standby database / streaming replication.

You mean just a single dedicated database server? If "yes", nothing changes to the configuration file.

Thanks much on your quick reply. If I understood it correctly, If I am setting up it as only dedicated primary server then no changes in conf file required. If I will have to set up the new stand by to point this new primary then I will have to make the configuration file changes.
