Bruce Momjian c155f654b4 intarray: return empty zero-dimensional array for an empty array ...

Previously a one-dimensional empty array was returned, but its text
representation matched a zero-dimensional array, and there is no way to
dump/reload a one-dimensional empty array.

BACKWARD INCOMPATIBILITY
