It's certainly worth looking into. I would not want to prejudge how
to fix such issues; I think the best way to proceed would be to create
a list of the problems first.
One other point worth making is that we don't always consider SQL
compliance to be a hard requirement that trumps every other
consideration. An example is case-folding of identifiers; it's
been pretty well agreed that between readability and backwards-
compatibility considerations, we simply aren't going to switch over
to doing it exactly like the spec. So any proposed tweaks in this area
would be considered as tradeoffs between better spec compliance and
other goals.
