Fine with me.

I think it helps if you consider IF EXISTS an attribute of the command,
not an attribute of the command parameters.

Now we should be aware that this sort of sets a precedent for ALTER
TABLE IF EXISTS ... DROP ANYTHING ... and similar composite commands.

If might be worth checking other SQL databases.  We stole the IF EXISTS
from somewhere, I believe.
