I pushed a fix for that separately.  I remembered that we had decided
to use MatchAnyExcept("...") instead of "!...", so I did it that way.

Yes, there is room to make it smarter.

Good question.

I am not a fan of doing anything at all to support alternative
spellings for keywords etc, even though I personally use British
spelling in most contexts outside PostgreSQL source code.  We don't
support MATERIALISED, CATALOGUE, BACKWARDS/FORWARDS (with an S), etc,
so I don't know why we have this one single word ANALYSE from a
different spelling system than the one used by SQL.
