CREATE INDEX and DROP INDEX are implemented by calling ALTER TABLE with
the proper arguments. This isn't very fast but it should work for most
cases.
In the future ALTER TABLE will notice that only added indexes
and create these one by one for the existing table without having to do
a full rebuild.
One should normally create all indexes with CREATE TABLE or ALTER TABLE.
