TODO: maybe make the dialect args into [dialect], then each test
checks all the dialects mentioned work, and all the dialects not
mentioned give a parse error. Not sure if this will be too awkward due
to lots of tricky exceptions/variationsx.

this just checks the sql parses without error, mostly just a
intermediate when I'm too lazy to write out the parsed AST. These
should all be TODO to convert to a testqueryexpr test.
