title: Combining 2 views into one in PostgreSQL
body: <p>I need to do something completely insane. I have 2 views that have the same number of columns (different column names though except the ID column) and they both happen to have
  2 existing UNION queries. From my understanding <code>UNION</code> and <code>UNION ALL</code> only work when combining 2 <code>SELECT</code> queries, here I'm trying to combine 4 of them! Aka the 2 views.</p>
