- **- mapname1 systemname1 pguser1**
- **- mapname1 systemname2 pguser2**
- **pg\_ctl\_timeout**: How long should pg_ctl wait when doing ``start``, ``stop`` or ``restart``. Default value is 60 seconds.
- **use\_pg\_rewind**: try to use pg\_rewind on the former leader when it joins cluster as a replica.
- **use\_pg\_rewind**: try to use pg\_rewind on the former leader when it joins cluster as a replica. Either the cluster must be initialized with ``data page checksums`` (``--data-checksums`` option for ``initdb``) and/or ``wal_log_hints`` must be set to ``on``, or ``pg_rewind`` will not work.
- **remove\_data\_directory\_on\_rewind\_failure**: If this option is enabled, Patroni will remove the PostgreSQL data directory and recreate the replica. Otherwise it will try to follow the new leader. Default value is **false**.
- **remove\_data\_directory\_on\_diverged\_timelines**: Patroni will remove the PostgreSQL data directory and recreate the replica if it notices that timelines are diverging and the former primary can not start streaming from the new primary. This option is useful when ``pg_rewind`` can not be used. While performing timelines divergence check on PostgreSQL v10 and older Patroni will try to connect with replication credential to the "postgres" database. Hence, such access should be allowed in the pg_hba.conf. Default value is **false**.
- **replica\_method**: for each create_replica_methods other than basebackup, you would add a configuration section of the same name. At a minimum, this should include "command" with a full path to the actual script to be executed. Other configuration parameters will be passed along to the script in the form "parameter=value".
