 ## Configuration
 
 1. Add these required options to the `postgresql.conf` of each instance in the cluster.
- ```sh

-                            # logical replication and will not work otherwise
- max_connections = 100
- max_prepared_transactions = 300 # all transactions are implicitly two-phase, so that's
-                                 # a good idea to set this equal to max_connections*N_nodes.
- max_wal_senders = 10       # at least the number of nodes
- max_replication_slots = 10 # at least the number of nodes
- max_worker_processes = 250 # Each node has:
-                            #   N_nodes-1 receiver
-                            #   N_nodes-1 sender

-                            # Also transactions executed at neighbour nodes can cause spawn of
-                            # background pool worker at our node. At max this will be equal to

 2. Allow replication in `pg_hba.conf`.
