According to SQL:2003 and SQL:2008 (and the draft standard, if that
matters) in section 5.2 of Foundation, both NEW and OLD are reserved
words, so we're going to need to re-reserve them to comply.

Sadly, this will cause problems for people who have tables with those
names, but we've introduced incompatibilities (in 8.3, e.g.) that hit
a much bigger part of our user base much harder than this.  When we do
re-reserve, we'll need to come up with a migration path.

Cheers,
David.
