I have a question about how ARRAY_PREPEND and ARRAY_CAT.
Should ARRAY_PREPEND(null, ARRAY[1,2,3]) or ARRAY_CAT(null, ARRAY[1,2,3])
return null or ARRAY[1,2,3]?
> Array modification functions should require two arguments

> ARRAY_APPEND, ARRAY_PREPEND, and ARRAY_CAT should require two arguments.
> Also, if the second argument is null, we need to make sure not to have the
> entire expression return null (but instead it should return the first
> argument). To accomplish this, we need to have a ParseNode that overrides the
> method controlling this and ensure it's used for these functions.
