title: Remove array values in pgSQL
body: <p>Is there a way to remove a value from an array in pgSQL? Or to be more precise, to pop the last value? Judging by <a href="http://www.postgresql.org/docs/8.4/interactive/functions-array.html" rel="noreferrer">this list</a> the answer seems to be no. I can get the result I want with an additional index pointer, but it's a bit cumbersome.</p>
