Can I clone database from previous version of Odoo (I have Odoo 8)? If "yes", by what method?
I tried exporting and re-importing data but I have an error.

You can take the database using pg_dump dbname > db_filename.sql
although you cannot use the same database in other odoo versions since there is a lot of schematic changes in your database that is different in different versions of odoo.
In order to do so you need to migrate the database from one version to another.
There is OpenUpgrade that allows migration from odoo 8 to 9.
