title: What to do when a Google Cloud SQL postgres server upgrade (to a bigger machine) takes considerably longer than "a few minutes"?
body: <p>We upgraded our Google Cloud SQL postgres server to a bigger machine and the upgrade is not terminating. In our experience, this usually takes less than 5 minutes, but we'ven been waiting for about 1.5 hours now and nothing is happening. There are no logs after the server shut down(except for failed connection attempts). We cannot switch to the failover, because  there is already an operation in progress (namely the upgrade that's causing the problem in the first place). Restarting is disabled because the operation is in progress. It seems like there's nothing we can do right now, except maybe apply the last backup, though we're not sure if that's even possible while an operation is in progress.</p>
  
  <p>Is there anything we can do to restart the DB or fix the problem?</p>
