# How-Tos

How-to guides for managing PostgreSQL clusters using the DCD.

{% hint style="warning" %}
**Important:**

* Effective **September 28, 2026**, **PostgreSQL v1** functionality will be decomissioned. Use **PostgreSQL v2** to create and manage clusters using the [<mark style="color:blue;">DCD</mark>](/cloud/databases/postgresql/how-tos/v2.md) or the [<mark style="color:blue;">API</mark>](https://docs.ionos.com/cloud/api-reference/databases/postgresql-v2/).
* Cluster creation using **PostgreSQL v1** API is deprecated effective **July 15, 2026**.
* Existing PostgreSQL v1 clusters will be automatically migrated to the new PostgreSQL v2 infrastructure starting **July 29, 2026**. No user action is required and we will notify you before the migration. If you prefer to migrate earlier, see [<mark style="color:blue;">Manual migration</mark>](/cloud/databases/postgresql/how-tos/migrate-from-v1-v2.md#manual-migration).
  {% endhint %}

## What can you do with the PostgreSQL v2 engine in the DCD?

With the PostgreSQL v2 engine in the DCD, you can:

* Create a PostgreSQL v2 cluster. Cluster creation is no longer supported in v1.
* View the list of clusters, a cluster's details, and its metrics.
* Update cluster properties, configuration, resources, and maintenance settings.
* Clone an existing cluster.
* Restore a cluster from a backup to a specific point in time.
* Delete a cluster that is no longer required.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ionos.com/cloud/databases/postgresql/how-tos.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
