Re: how to fail over slave to master
In verison 12, postgresql.auto.conf to replace recovery.conf
do I need to run
1. pg_ctl promote -D Pg_data (in slave?)
1. pg_ctl promote -D Pg_data (in slave?)
2. pg_rewind --target -pg_data=master_server (aliase hostname of master) --source-server="port=5433 user=replica dbname=postgres" --progress
3. change postgresql.cond parameter, primary_slot_name ='main'
do I need to run pg_rewind for each dbname?
I don't understand why pg_rewind set the port=5433 not 5432?

1) The parameters that used to be set in recovery.conf are instead set in postgresql.conf in 12 & above.
2) They are set on your replica; otherwise it would not come up as a replica. They are not needed in a master.
