Replication rolling back to normal.

[Dasitha Karunajeewa <dasitha@xxxxxxxxxxxxxxx>]

Dear Team,

I have installed PostgreSQL 9.6 on two servers. One is master and other is for slave server. Current setup as follows.

• Master Server - pgmaster
• Salve Server - pgslave                 

To implement this I have followed this article https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-on-postgresql-on-an-ubuntu-12-04-vps

Master Slave combination is working fine. 

when I create a file at the file trigger location ex: /tmp/postgresql.trigger.5432 on pgslave server, it started accepting read and as well as write request which is perfectly correct.

What I want to know is how to switch them back to the normal status. That means pgmaster need to be the Master server which acept the writed and pgslave that accepts only reads along with the replication.

Regards,

Dasitha.
