-- Given a create table specifying a constraint

-- Then we errored out

-- Given a create partition table table specifying a constraint
create table exclusion_constraints_pt1(a int, b int, EXCLUDE (b WITH =)) partition by range(a) (start(1) end(4) every(1));

-- And we alter table to add constraints
