### Prepare Postgres
Prepare a KubeDB Postgres cluster using this [tutorial](/docs/guides/postgres/clustering/streaming_replication.md), or you can use any externally managed postgres but in that case you need to create an [appbinding](/docs/guides/pgbouncer/concepts/appbinding.md) yourself. In this tutorial we will use 3 node Postgres cluster named `ha-postgres`.
