A standby node *needs* to be based on a base backup of its primary or
the node it connects to (it can be as well a slave in a cascading
configuration). One of the reasons being that they need to share the
same system identifier (Database system identifier output in
pg_controldata). Using initdb on multiple nodes to set up a cluster
will simply not satisfy this condition, and your cluster setup will
fail. More details here:
