示例1: upgrade

# NOTE(sileht): mysql can't delete an index on a foreign key
# even this one is not the index used by the foreign key itself...
# In our case we have two indexes fk_resource_history_id_resource_id and
# and ix_resource_history_id, we want to delete only the second, but mysql
# can't do that with a simple DROP INDEX ix_resource_history_id...
# so we have to remove the constraint and put it back...
