You can do whatever you want, 1 cluster per database, 1 cluster per VM
or all in one according to your load or something in between.
I'm basically using a list of databases either in host_vars or inventories
and include_vars: dir: to create clusters and databases per host or per
environment.
To be more specific, this list is for a cluster name (default is main
on Debian) and this cluster is combined to a port variables to make
more clusters per host with 1 or more databases per host.
All this with streaming replication+wal shipping, backup and restore
configured properly for each cluster.
So what's your question about ansible ? :-)
