# Managed Service for PostgreSQL API, gRPC: DatabaseService.Update

Updates the specified PostgreSQL database.

## gRPC request

**rpc Update ([UpdateDatabaseRequest](#yandex.cloud.mdb.postgresql.v1.UpdateDatabaseRequest)) returns ([operation.Operation](#yandex.cloud.operation.Operation))**

## UpdateDatabaseRequest {#yandex.cloud.mdb.postgresql.v1.UpdateDatabaseRequest}

```json
{
  "cluster_id": "string",
  "database_name": "string",
  "new_database_name": "string",
  "update_mask": "google.protobuf.FieldMask",
  "extensions": [
    {
      "name": "string",
      "version": "string"
    }
  ],
  "deletion_protection": "google.protobuf.BoolValue"
}
```

#|
||Field | Description ||
|| cluster_id | **string**

Required field. ID of the PostgreSQL cluster to update a database in.
To get the cluster ID use a [ClusterService.List](../Cluster/list.md#List) request.

The maximum string length in characters is 50. ||
|| database_name | **string**

Required field. Name of the database to update.
To get the name of the database use a [DatabaseService.List](list.md#List) request.

The maximum string length in characters is 63. Value must match the regular expression ` [a-zA-Z0-9_-]* `. ||
|| new_database_name | **string**

Optional. New name of the database.

The maximum string length in characters is 63. Value must match the regular expression ` [a-zA-Z0-9_-]* `. ||
|| update_mask | **[google.protobuf.FieldMask](https://developers.google.com/protocol-buffers/docs/reference/csharp/class/google/protobuf/well-known-types/field-mask)**

Field mask that specifies which fields of the Database resource should be updated. ||
|| extensions[] | **[Extension](#yandex.cloud.mdb.postgresql.v1.Extension)**

PostgreSQL extensions that should be enabled for the database.

If the field is sent, the list of enabled extensions is rewritten entirely.
Therefore, to disable an active extension you should simply send the list omitting this extension. ||
|| deletion_protection | **[google.protobuf.BoolValue](https://developers.google.com/protocol-buffers/docs/reference/csharp/class/google/protobuf/well-known-types/bool-value)**

Deletion Protection inhibits deletion of the database

Default value: `unspecified` (inherits cluster's deletion_protection) ||
|#

## Extension {#yandex.cloud.mdb.postgresql.v1.Extension}

#|
||Field | Description ||
|| name | **string**

Name of the extension, e.g. `pg_trgm` or `pg_btree`.
Extensions supported by Managed Service for PostgreSQL are [listed in the Developer's Guide](../../../operations/extensions/cluster-extensions.md). ||
|| version | **string**

Version of the extension. The setting is deprecated and has no effect. ||
|#

## operation.Operation {#yandex.cloud.operation.Operation}

```json
{
  "id": "string",
  "description": "string",
  "created_at": "google.protobuf.Timestamp",

  }
  // end of the list of possible fields
}
```

An Operation resource. For more information, see [Operation](../../../../api-design-guide/concepts/operation.md).

#|
||Field | Description ||
|| id | **string**

ID of the operation. ||
|| description | **string**

Description of the operation. 0-256 characters long. ||
|| created_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

Creation timestamp. ||
|| created_by | **string**

ID of the user or service account who initiated the operation. ||
|| modified_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

The time when the Operation resource was last modified. ||
|| done | **bool**

If the value is `false`, it means the operation is still in progress.
If `true`, the operation is completed, and either `error` or `response` is available. ||
|| metadata | **[UpdateDatabaseMetadata](#yandex.cloud.mdb.postgresql.v1.UpdateDatabaseMetadata)**

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any. ||
|| error | **[google.rpc.Status](https://cloud.google.com/tasks/docs/reference/rpc/google.rpc#status)**

The error result of the operation in case of failure or cancellation.

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
If `done == false` and there was a failure detected, `error` is set.
If `done == true`, exactly one of `error` or `response` is set. ||
|| response | **[Database](#yandex.cloud.mdb.postgresql.v1.Database)**

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is [google.protobuf.Empty](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Empty).
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
If `done == false` and there was a failure detected, `error` is set.
If `done == true`, exactly one of `error` or `response` is set. ||
