This would make more sense if all of multibyte, locale, and NLS became
defaults in one release. I haven't quite sold people in the second item
yet, although I have a design how to do that (see below). And the third,
well who knows...
Perhaps we could make it a release goal for 7.3 to
* Optimize i18n stuff to have a minimal performance penalty when it's not
used. (locale=C etc.)
* Make i18n stuff sufficiently well-behaved to make it the default.
(Especially, add initdb options and GUC parameters to set the locale.
Don't rely on environment variables -- too complicated.)
Meanwhile, quadratic performance penalties (or so it seems) for LIKE
expressions aren't exactly a "minor" problem.
