/**
* There are two types of tests in here, and they answer two different
* questions about MergeWindows (MW):
*
* 1) Is MW working as it's supposed to be? The tests running the minimal
* set of optimizers can tell us this.
* 2) Has some other optimizer changed the plan in such a way that MW no
* longer merges windows with identical specifications because the plan
* that MW sees cannot be optimized by MW? The test running the full set
* of optimizers answers this, though it isn't actually meaningful unless
* we know the answer to question 1 is "yes".
*
* The tests that use only the minimal set of optimizers are closer to true
* "unit" tests in that they verify the behavior of MW with as few
* external dependencies as possible. Those dependencies to include the
* parser and analyzer, so the phrase "unit" tests should be taken with a
* grain of salt. Using the parser and anayzler instead of creating plan
* nodes by hand does have a couple of advantages over a true unit test:
* 1) The tests are more self-maintaining.
* 2) They're a lot easier to read.
* 3) It's a lot less typing.
*
* The test that runs with all of the optimzers acts as an integration test
* and ensures that MW is effective when run with the complete set of
* optimizers.
