# Runbook — PostgreSQL

## Health

```bash
sudo systemctl status postgresql
```

## Connections

Inspect active connections before maintenance.

## Disk

```bash
df -h
```

## Backup Before Risky Changes

Always create a verified backup before:

- destructive migrations
- ownership changes
- restore operations
- major data repair
- production imports

## Restore Principle

Restore to a controlled target first when practical.

Verify:

- database owner
- schema owner
- application role
- privileges
- extensions
- migration state

before returning the database to application traffic.
