The problem with my approach is that other dialects of SQL may want a different
behavior
{quote}
Yes, but let's do it in two steps. First, and most important, let's have an
agreed (and documented) default behavior. Second, provide a way for dialects
(actually I believe we're talking about conformances) to override.
Reading the code, I see that CALCITE-3550 had that second goal. If it doesn't
work for you, should we log a new case proposing an improved extensibility
mechanism?
