  == Supported PostgreSQL topologies
  
  The PostgreSQL connector can be used with a standalone PostgreSQL server or with a cluster of PostgreSQL servers. 
  
  As mentioned link:#limitations[in the beginning], PostgreSQL 9.6 only supports logical replication slots on `master` servers. This means that a replica in a PostgreSQL cluster cannot be configured for logical replication, and consequently that the Debezium PostgreSQL Connector can only connect and communicate with the master server. Should this server fail, the connector will stop. When the cluster is repaired, if the original master server is once again promoted to `master`, the connector can simply be restarted. However, if a different PostgreSQL server _with the plugin and proper configuration_ is promoted to `master`, the connector configuration must be changed to point to the new `master` server and then can be restarted.
