title: Postgres Query based on Delimited String
body: <p>we have a column in one of our tables that consist of a delimited string of ID's, like this:   72,73,313,502.</p>
  <p>What I need to do in the query, is to parse that string, and for each ID, join it to another table.   So in the case of this string, I'd get 4 rows.......like the ID and the name from the other table.</p>
  <p>Can this be done in a query?</p>
