Re: How may I keep prepended array items positive?

I want to use it like this...

UPDATE SET _array = {1,2,3} || _array;

Which if _array had {1} in it, I'd get something like
[-2:1]{1,1,2,3} as the range... I only want it to push
the existing values to the right so I'd have
[1:4]{1,1,2,3}

I don't have a pgsql on this box to show output..
