title: ActiveRecord - Possible to pluck columns from a specific row? (Also, strange issues with select and quotation marks)
body: <p>I am trying to get a number of columns from a specific row via ActiveRecord like so (all examples are simplified for clarity):</p>
  
  <p><code>User.pluck(:id, :name, :date_joined, :field_containing_json)</code></p>
  
  <p>Previously, I was using a select statement which for some reason didn't work unless each column was enclosed in quotation marks:</p>
  
  <p><code>User.find(id).select("id, name, date_joined, field_containing_json")</code> fails for some reason and throws a <code>PG::SyntaxError: ERROR</code> while <code>User.find(id).select("id", "name", "date_joined", "field_containing_json")</code> works.</p>
  
  <p>Thus this is a somewhat two-pronged question:</p>
  
  <ol>
  <li>Why would one need to encapsulate each column name in quotation marks when using <code>select</code>?</li>
  <li>Is there a way to <code>pluck</code> a specific row? <code>User.find(id).pluck(:id, :name ...)</code> throws <code>NoMethodError</code> </li>
  </ol>
