Proposed fix for Bug #15259 (invalid empty array returned by intarray "&" operator)
The attached patch fixes Bug #15259 [1]/messages/by-id/153053285112.13258.434620894305716755@wrigleys.postgresql.org in the intarray module, making the
'&' array intersection operator return proper zero-dimensional empty arrays
instead of one-dimensional, zero-length "empty" arrays.
In [2]/messages/by-id/20570.1506198383@sss.pgh.pa.us this problem was addressed by changing the behaviour of
construct_[md_]array(), but the intarray module does not use these
functions. The patch I propose contains the relevant fixes to the
intarray module, along with regression tests.
