Change subject: Renamed conjunct_ordering.test to 
primitive_conjunct_ordering.test in targeted-perf
......................................................................


Patch Set 1:

This change should work for reordering join conjuncts, not just scan conjuncts, 
but only conjuncts that appear in the same list, eg. hash predicates can be 
reordered with other hash predicates but not with "other" predicates.

I'm not sure what you mean that the query is not valid. Our plan for the 
regular tcph-q19 query applies the predicates at the join also. The only change 
I made was adding another predicate, since the original query only has two, 
with one being a "hash" predicates and the other being an "other predicate so 
we couldn't reorder them.
