  // Always get the language-specific alias before the language-neutral one.
  // For example 'de' is less than 'und' so the order needs to be ASC, while
  // 'xx-lolspeak' is more than 'und' so the order needs to be DESC. We also
  // order by pid ASC so that fetchAllKeyed() returns the most recently
  // created alias for each source. Subsequent queries using fetchField() must
  // use pid DESC to have the same effect.
