You know, that would explain a lot. Since this was only done in October, I
wouldn't have noticed it. And it explains why I couldn't get various
changes in my code to actually have any effect...
Oh well, it was a fun coding exercise ;) Feel free to remove the ADD UNIQUE
stuff from command.c to see if the parser will handle it. However, your
commit message also just implies that all you fixed was ADD PRIMARY KEY???
