# Manage Postgres

Change CPU, memory, disk size or high availability. PostgreSQL 18 is the only supported major version in preview; the CLI update command does not change the major version.

For a Postgres managed in Git, update the manifest. A later `nais apply` can overwrite changes made through the CLI or Console.

**GitOps**

Edit the Postgres manifest in your repository:

```yaml
version: v1
type: Postgres
name: <POSTGRES-NAME>
spec:
  majorVersion: "18"
  highAvailability: true
  resources:
    cpu: 100m
    memory: 512Mi
    diskSize: 20Gi
```

Push the change. The next workflow run applies the new desired state. See [Deploy manifest changes without rebuilding](/build/how-to/deploy-pipeline.md#deploy-manifest-changes-without-rebuilding) for a complete pipeline example.

**CLI**

Update one or more settings:

```bash
nais postgres update <POSTGRES-NAME> \
  --team <TEAM> \
  --environment <ENVIRONMENT> \
  --disk-size 20Gi
```

The update command accepts `--high-availability true|false`, `--cpu`, `--memory` and `--disk-size`. Omitted settings stay unchanged.

**Console**

1. Open your team in [Nais Console](https://console.nais.io) and select **Postgres**.
2. Select the database.
3. Open **Actions → Edit**.
4. Update the form and select **Save changes**.

Changes are applied asynchronously. Follow the status on the database's page in [Nais Console](https://console.nais.io).
