Doc: improve example for intarray's uniq() function.
The previous entry invited confusion between what uniq() doesby itself and what it does when combined with sort(). The latterusage is pretty useful so we should show it, but add an additionalexample to clarify the results of uniq() alone.Per suggestion from Martin Kalcher. Back-patch to v13, wherewe switched to formatting that supports multiple examples.Discussion:https://postgr.es/m/165407884456.573551.8779012279828726162@wrigleys.postgresql.org
