Welcome,
I am planning to do a linux-ha cluster. Is replication applicable in a
solution like this? The main questions are that after the main node
fails and the slave node becomes the master:
-- a postmaster, started as slave, will be able to work standalone?
-- after repairing the main node, it will become the slave node, so the
aforementioned postmaster shall become master. Is this possible?
Thanks
