We are planning to change our single node environment to multi node.
We have 256 GN of RAM in existing single node environment which we will keep as reload/Central node.On top of it we will add 3 nodes ( 2 consumer nodes and 1 dev node) so we need to know
1) what should be the RAM for the additional rim node? it should be same as central node or we can keep as minimum as recommended in prerequisites
2) We have unbundled postgres running on existing single node so do we need to install postgres on each rim node as well?
