title: how to access postgres from mysql?
body: <p>Is it possible to access a Postgres database from MySQL, so that I could run a single query that does joins across tables in both databases?</p>
  
  <p>For example:</p>
  
  <pre><code>SELECT * FROM postgres.db1.table1 as t1, mysql.db2,table2 WHERE t1.id=t2.id;
  </code></pre>
