# Manage a Database

Everything here lives in the database’s **Settings**, and requires the database to be **Active** — while it’s provisioning, updating, or deleting, changes are temporarily disabled.

## Resize compute and storage

**Compute** (CPU/memory tier) and **storage** are changed — and saved — independently:

-   **Scale compute** by moving the instance to a larger tier. Reducing resources isn’t supported yet — you can only scale up.
-   **Grow storage** to a larger size. Storage is **grow-only**, and you can’t select a size below what the instance already uses — so raise it deliberately.

## Upgrade the PostgreSQL version

Change the **engine version** from the General settings when you’re ready to move to a newer major version.

Heads up

Resizing, storage growth, version upgrades, and network changes can briefly restart the instance or affect its availability. Apply them during a maintenance window where you can.

## Rotate the admin password

If you’ve lost the admin password — or just want to retire it — use **Rotate password** on the database’s overview. Rotation is available only while the database is **Active**.

Rotating generates a new password and shows it **once**: copy it immediately, it won’t be shown again. The database moves to **Updating** while the change rolls out — the current password keeps working until the database returns to **Active**, at which point the new one takes effect.

Heads up

Any projects connected with the old password may lose access after rotation — update their configuration with the new password. Projects [linked](https://salus.cloud/docs/deployments/databases/connect/) to the database get the refreshed credentials through their injected variables.

## Delete a database

Deleting lives in the settings **Danger Zone**, and asks you to type the database’s name to confirm.

Careful

Deleting a database permanently deletes all data, configurations, and backups. This action can’t be undone.

## Troubleshooting

-   **Settings are disabled.** Changes are blocked while the database is provisioning, updating, or deleting — wait for it to return to **Active**.
-   **You can’t pick a smaller tier or storage size.** Downsizing isn’t supported: compute only scales up, and storage can’t go below current usage.
-   **Apps lost database access after a rotation.** Update any hand-configured connection details with the new password; linked projects receive it automatically.
