Neil, I'm not advocating a change. As long as Postgres sequences
don't look like SQL2003 sequence generators there is no problem, if
they behave differently. OTOH if we have standard syntax, I'd prefer
to have standard semantics, too. Maybe we can have classic Postgres
syntax (nextval('...')) with classic Postgres behaviour and SQL2003
syntax (NEXT VALUE FOR ...) with SQL2003 behaviour side by side?
CURRENT_TIMESTAMP is another issue, because it looks like standard
SQL, but ...
