Restoring schema and data separately is guaranteed to be less efficient
than restoring a combined dump. An option to omit indexes from the
schema dump will not fix this. Indeed it will arguably make things
worse --- in the first place there are severe performance issues
associated with unindexed foreign-key checks, and in the second place
there is the foot-gun problem that you might forget to re-add the
indexes at all.
I think the right question to ask here is "why are you so intent on
using separate schema/data restores?" That's not the recommended way
to go about things, and it never will be.
