Commit716ea626aattempted to fix the problem of building 1-D zero-size arrays once and for all. But it turns out that contrib/intarray has some code that doesn't use construct_array() but just builds arrays by hand, so it didn't get the memo. This appears to affect all of subarray(), intset_subtract(), inner_int_union(), inner_int_inter(), and intarray_concat_arrays(). Back-patch into v11. In the past we've not back-patched this type of change, but since v11 is still in beta it seems all right to include this fix in it. Besides it's more consistent to make the fix in v11 where716ea626aappeared. Report and patch by Alexey Kryuchkov, some cosmetic adjustments by me Report: https://postgr.es/m/153053285112.13258.434620894305716755@wrigleys.postgresql.org Discussion: https://postgr.es/m/CAN85JcYphDLYt4CpMDLZjjNVqGDrFJ5eS3YF=wLAhFoDQuBsyg@mail.gmail.com
