title: Can multiple instances of temporal be backed by the same database?
body: <p>This is a &quot;Yes/No&quot; question: Can multiple instances of temporal be backed by the same database?</p>
  <p>I want to use a single (HA, geo-redundant) Cloud SQL to store workflow state with multiple (geo-redundant) workers sharing that DB.</p>
  <p>I can't find anything in the documentation that answers this question.</p>
