I searched over the source tree to see if there is a similar buggy bsearch comparator and didn’t find any. However, I
founda set of comparators in common/int.h, so I think it’s better to use them here:
```
diff --git a/contrib/intarray/_int_selfuncs.c b/contrib/intarray/_int_selfuncs.c
index c3e19cdf27f..80faac8ae71 100644
