What do you mean?
With a simple scenario, say
3 nodes and 3 pgSQL clusters
what would be best possible way - I'm thinking most gentle
at the same time, if that makes sense.
I'm not sure it answers your question (as I don't understand it), but here is a
doc explaining how to create and move two IP supposed to each start on
secondaries, avoiding the primary node if possible, as long as secondaries nodes
exists

Apologies, perhaps I was quite vague.
I was thinking - having a 3-node HA cluster and 3-node
single-master->slaves pgSQL, now..
say, I want pgSQL masters to spread across HA cluster so I
theory - having each HA node identical hardware-wise -
masters' resources would nicely balance out across HA cluster.
