- First set the configuration options in <code class="filename">postgresql.conf</code>:
- </p><pre class="programlisting">
- wal_level = logical
- </pre><p>
- The other required settings have default values that are sufficient for a
- basic setup.
- </p><p>
- <code class="filename">pg_hba.conf</code> needs to be adjusted to allow replication
- (the values here depend on your actual network configuration and user you
- want to use for connecting):
- </p><pre class="programlisting">
- host all repuser 0.0.0.0/0 md5
- </pre><p>
- </p><p>
- Then on the publisher database:
- </p><pre class="programlisting">
- CREATE PUBLICATION mypub FOR TABLE users, departments;
- </pre><p>
- </p><p>
- And on the subscriber database:
- </p><pre class="programlisting">
- CREATE SUBSCRIPTION mysub CONNECTION 'dbname=foo host=bar user=repuser' PUBLICATION mypub;
- </pre><p>
- </p><p>
- The above will start the replication process, which synchronizes the
- initial table contents of the tables <code class="literal">users</code> and
- <code class="literal">departments</code> and then starts replicating
- incremental changes to those tables.
