Hyunsik Choi updated TAJO-216:
------------------------------
Attachment: TAJO-216.Hyunsik.131001.patch
I've improved the latest patch. In this patch, I've improved unit tests and
cleanup some parts of physical operators.
Also, I vote +1 for Camelia's work.
Camelia's patch contains LeftOuterHashJoin, LeftOuterNLJoin,
RightOuterMergeJoin, FullOuterHashJoin, and FullOuterMergeJoin. According to
unit tests included in his patch and my test results, they work well.
However, those operators and FilterPushDownRule seem to need more optimization
and cleanup. After it is committed to master branch, I'll continue to improve
them if there is no objection.
