title: does postgresql array type preserve order of array?
body: <p>I read over the docs for PostgreSQL v 9.3 arrays (<a href="http://www.postgresql.org/docs/9.3/static/arrays.html" rel="noreferrer">http://www.postgresql.org/docs/9.3/static/arrays.html</a>), but I don't see the question of ordering covered. Can someone confirm that Postgres preserves the insertion order/original order of an array when it's inserted into an array column? This seems to be the case but I would like absolute confirmation.</p>
  
  <p>Thank you.</p>
