Add query 19 to TPC-H regression tests

[Dandandan]

Which issue does this PR close?

Closes #58

Rationale for this change

The query failed before because of a missing cross join. The query runs now (but takes an almost infinite time to run because of the cross join, which probably is a bug or missing optimization somewhere in the planner).

Looks good to me @Dandandan -- thanks.

In order to get Q19 to work, the optimizer needs to be clever enough to recognize that p_partkey = l_partkey which appears in each of the three clauses is a join predicate. The query shouldn't be doing a CROSS JOIN, it should be doing an INNER JOIN on p_partkey = l_partkey

Note this is Q19:

select
sum(l_extendedprice * (1 - l_discount) ) as revenue
from
lineitem,
part
where
(
p_partkey = l_partkey
and p_brand = ‘[BRAND1]’
and p_container in ( ‘SM CASE’, ‘SM BOX’, ‘SM PACK’, ‘SM PKG’)
and l_quantity >= [QUANTITY1] and l_quantity <= [QUANTITY1] + 10
and p_size between 1 and 5
and l_shipmode in (‘AIR’, ‘AIR REG’)
and l_shipinstruct = ‘DELIVER IN PERSON’
)
or
(
p_partkey = l_partkey
and p_brand = ‘[BRAND2]’
and p_container in (‘MED BAG’, ‘MED BOX’, ‘MED PKG’, ‘MED PACK’)
and l_quantity >= [QUANTITY2] and l_quantity <= [QUANTITY2] + 10
and p_size between 1 and 10
and l_shipmode in (‘AIR’, ‘AIR REG’)
and l_shipinstruct = ‘DELIVER IN PERSON’
)
or
(
p_partkey = l_partkey
and p_brand = ‘[BRAND3]’
and p_container in ( ‘LG CASE’, ‘LG BOX’, ‘LG PACK’, ‘LG PKG’)
and l_quantity >= [QUANTITY3] and l_quantity <= [QUANTITY3] + 10
and p_size between 1 and 15
and l_shipmode in (‘AIR’, ‘AIR REG’)
and l_shipinstruct = ‘DELIVER IN PERSON’
);
