Has to be a multiple of 1024. * `storage_size` - (Required)\[int] The amount of storage per instance in MB. Has to be a multiple of 2048. * `storage_type` - (Required)\[string] SSD, SSD Standard, SSD Premium, or HDD. Value "SSD" is deprecated, use the equivalent "SSD Premium" instead. This attribute is immutable(disallowed in update requests). * `connection_pooler` - (Optional)\[object] * `enabled` - (Required)\[bool] * `pool_mode` - (Required)\[string] Represents different modes of connection pooling for the connection pooler. * `connections` - (Required)\[string] Details about the network connection for your cluster. * `datacenter_id` - (Required)\[true] The datacenter to connect your cluster to. * `lan_id` - (Required)\[true] The LAN to connect your cluster to. * `cidr` - (Required)\[true] The IP and subnet for the database. Note the following unavailable IP ranges: 10.233.64.0/18, 10.233.0.0/18, 10.233.114.0/24. Please enter in the correct format like IP/Subnet, exp: 192.168.10.0/24. See [Private IPs](https://www.ionos.com/help/server-cloud-infrastructure/private-network/private-ip-address-ranges/) and [Configuring the network](https://docs.ionos.com/cloud/compute-engine/networks/how-tos/configure-networks). * `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. Available locations: `de/fra`, `us/las`, `us/ewr`, `de/txl`, `gb/lhr`, `gb/bhx`, `es/vit`, `fr/par`, `us/mci`, `de/fra/2`. This attribute is immutable (disallowed in update requests). * `backup_location` - (Optional)(Computed)\[string] The IONOS Object Storage location where the backups will be stored. Possible values are: `de`, `eu-south-2`, `eu-central-2`. This attribute is immutable (disallowed in update requests). * `display_name` - (Required)\[string] The friendly name of your cluster. * `maintenance_window` - (Optional)(Computed) A weekly 4 hour-long window, during which maintenance might occur * `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, STRICTLY\_SYNCHRONOUS. The SYNCHRONOUS value has been deprecated for create 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.*** ## Import Resource DbaaS Postgres Cluster can be imported using the `cluster_id`, e.g. ```shell terraform import ionoscloud_pg_cluster.mycluser cluster uuid ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ionos.com/terraform-provider/resources/dbaas_pgsql_cluster.md?ask= ``` The question should be specific, self-contained, and written in natural language.
