/**
* This tests verify joins order in plans generated for TPC-H queries using
* cost-based optimizer. They are intended to signal that a code change results
* in a change of generated plans.
*
* Most of the plans are currently suboptimal, so the tests results will likely
* change. They should be changed with care.
