# It is recommended to use at least three nodes in production deployment.
# But sometimes, there are only two nodes available, that's dual.yml for
#
# In this setup, we have two nodes, .10 (admin_node) and .11 (pgsql_priamry):
#
# If .11 is down, .10 will take over since the dcs:etcd is still alive
# If .10 is down, .11 (pgsql primary) will still be functioning as a primary if:
#   - Only dcs:etcd is down
#   - Only pgsql is down
# if both etcd & pgsql are down (e.g. node down), the primary will still demote itself.
