here is the same issue in table partitioning. Also, We might use the
syntax for our partitioning in the future. Just for reference,
DB2 uses EXCLUSIVE and INCLUSIVE keywords to specify boundaries.
CREATE TABLE ... PARTITION BY RANGE (...) (STARTING 0 EXCLUSIVE ENDING 100 INCLUSIVE)

I'm not sure it is the best syntax, but at least it's easy to read
for beginners and works with parentheses completion by text editors.
