But beware that logical replication requires PostgreSQL 10+ to work. You can still use the facility here and use a pg_dump | psql instead of logical replication.</p> <hr> <h2 id="define-a-migration-task">Define a Migration Task </h2> <p>You have to create a migration task definition file to use this playbook.</p>
