Extent elimination should work for CHAR(n)/VARCHAR(n) where n > 8

MCOL-4580 is doing extent elimination only for TEXT data type. We should do the same for CHAR where n > 8.

insert into test.t1 values (1, 'a'), (2, 'b'), (3, 'c'), (4, 'd'), (5, 'e'), (6, 'f'), (7, 'g'), (8, 'h'), (9, 'i');
SELECT calsettrace(1);
