No, scratch that: the problem is with that syntax, but in the columns
direction not the rows direction.  Since you've only got one column,
the TABLE syntax degenerates to one OUT param, which is treated as
though it were just the normal function result.  IOW, this function
shouldn't be returning a tuple at all, but just the array datum.
