Initializing your cluster

Before you begin

The data directory in Patroni must be owned by PostgreSQL superuser. Provide appropriate permissions to superuser as follows:
chown -R <SUPERUSER_NAME> <DATA_DIR>
Change data directory permissions so that only superuser can access with these commands:
chmod -R 700 <DATA_DIR>
Where, <DATA_DIR> is data directory path and name.
