Well, the title pretty much says it all, but here it is again: will
drop_table also remove any indexes for that table? Or do we need to
specify each index in the down migration?
I tried looking through the drop_table documentation, but didn't see
it mentioned. I also checked some of the more popular open source
projects, and they just drop_table, but don't remove any indexes.
Maybe rails takes care of this as part of its "magic" ?
