title: Get the QUERY PLAN without executing the query?
body: <p>I'm trying to optimize a long-running query in PostgreSQL 11.</p>
  
  <p>Every time I tweak the query or create some new indexes and then do an <code>EXPLAIN ANALYZE SELECT ...</code> to see if it worked, I have to wait a long time for the explanation.</p>
  
  <p>Is there a way to get the QUERY PLAN without actually executing the query, dare I say it, <em>just like the way it works in MySQL</em>?</p>
