-By default, PostgreSQL is installed as part of the chart. To use an external PostgreSQL server set `postgresql.enabled` to `false` and then set `postgresql.postgresqlHost` and `postgresql.postgresqlPassword`. The other options (`postgresql.postgresqlDatabase`, `postgresql.postgresqlUser` and `postgresql.postgresqlPort`) may also want changing from their default values.
