title: Redshift CREATE TABLE AS taking a long time from simple query
body: <p>When I run a certain query by itself, it is returning in LESS than 1 second.  When I try to create a table from that query using CREATE TABLE (name) AS, it is running up to 15 minutes with no completion.  </p>
  
  <p>I've made lots of tables as queries and not had this problem.  Should it take that much longer to make a table out of a query that on its own takes under one second to return?</p>
