Yes you have right, i don't realize this situation. But what about yust
leave empty bit set to True and don't discard the input value - items can
be sort and we can see the value - lower(int4range(4,4))
Hello,
default constructor for ranges use lower bound closed '[' and upper bound
open ')'. This is correct behavior, but when upper bound is same like
lower bound then range is empty. Mathematically is correct again - but in
database is lost information about range bounds (lower/upper is NULL).
