I was about to say that || would do it, but I see that's not quite
right:
regression=# SELECT ARRAY[1,2,3] || ARRAY[4,5,6];
?column?
-------------------
{{1,2,3},{4,5,6}}
(1 row)
Offhand, I would think that '{1,2,3,4,5,6}' would be what I'd
intuitively expect to get from "concatenating" these arrays.
Joe, do we really have this implemented per spec?
