## 32.9. Quick Setup

First set the configuration options in `postgresql.conf`:

    wal_level = logical

The other required settings have default values that are sufficient for a basic setup.

`pg_hba.conf` needs to be adjusted to allow replication (the values here depend on your actual network configuration and user you want to use for connecting):

    host     all     repuser     0.0.0.0/0     md5

Then on the publisher database:

    CREATE PUBLICATION mypub FOR TABLE users, departments;

And on the subscriber database:

    CREATE SUBSCRIPTION mysub CONNECTION 'dbname=foo host=bar user=repuser' PUBLICATION mypub;

The above will start the replication process, which synchronizes the initial table contents of the tables `users` and `departments` and then starts replicating incremental changes to those tables.
