AFAIK, SQL3 is not a recognized standard. We are converging (slowly)
on full support for SQL92, and we have some SQL99 features (and will
have more over time, no doubt).

I am not sure that we will ever be 100% compliant with either spec,
however. There are legacy things that we don't particularly want to
change --- for example, the choice of lower rather than upper case as
the default case folding for identifiers.
