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.
