I have a PostgreSQL repmgr Master-Slave setup with HOT standby enabled. In such repmgr configuration isnt it possible to configure the postgresql.conf in Primary and secondary DIFFERENTLY WHILE HOT STANDBY WILL BE ON. I mean parameters below:
etc MUST have to be same or different? If it is different then I saw the DB in secondary through some Errors. So, it ill require same H/W (Resources like RAM, CPU same) setup for both master-slave which is costly enough.
Please, I cant start my slave with less config and need a solution to work on less H/W Slave environment to be worked as HOT standby.
