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.
MySQL has a syntax in ALTER TABLE similar to PGSQL's DISABLE/ENABLE TRIGGER to do the same for KEYS. That way you will not run the risk of forgetting the INDEX (though you could still forget to enable them).
Potentially there could be a switch in pg_restore to create all KEYS as disabled initially and automatically enable them after the import is complete. Note that it could be smart enough to give special treatment to foreign keys.
