• location - (Required)[string] The physical location where the cluster will be created. This will be where all of your instances live. Property cannot be modified after datacenter creation. Possible values are: de/fra, de/txl, gb/lhr, es/vit, us/ewr, us/las. This attribute is immutable(disallowed in update requests).

  • time - (Required)[string]

  • day_of_the_week - (Required)[string]

• credentials - (Required)[string] Credentials for the database user to be created. This attribute is immutable(disallowed in update requests).

  • username - (Required)[string] The username for the initial postgres user. Some system usernames are restricted (e.g. "postgres", "admin", "standby")

  • password - (Required)[string]

• synchronization_mode - (Required) [string] Represents different modes of replication. Can have one of the following values: ASYNCHRONOUS, SYNCHRONOUS, STRICTLY_SYNCHRONOUS. This attribute is immutable(disallowed in update requests).

• from_backup - (Optional)[string] The unique ID of the backup you want to restore. This attribute is immutable(disallowed in update requests).

  • backup_id - (Required)[string] The unique ID of the backup you want to restore.

  • recovery_target_time - (Optional)[string] If this value is supplied as ISO 8601 timestamp, the backup will be replayed up until the given timestamp. If empty, the backup will be applied completely.

• dns_name - (Computed)[string] The DNS name pointing to your cluster.

• allow_replace - (Optional)[bool] When set to true, allows the update of immutable fields by destroying and re-creating the cluster."

  Warning: allow_replace - lets you update immutable fields, but it first destroys and then re-creates the cluster in order to do it. Set the field to true only if you know what you are doing.
