--------------------------------------------------------------------
{quote}SELECT a FROM table WHERE a = (SELECT a FROM table) GROUP BY a{quote}
Doesn't that look like an overkill?
Can you please generate {{(select a from table)}} instead?
Can you please add plan assertions to the test case, so it is obvious from the
test what is the expected plan for the given query?
