Sometimes after installing or removing some modules, there are some warnings in your console output when you run openerp-server.
Also if you have updated some modules from the nightly update, this can be a real time saver.

The following command can help you to make sure that everything is populated right in your database.
But before you do, make sure you have a backup of the database in the rare case something went wrong.

/opt/odoo/odoo/./openerp-server -d odoo -u all

Watch te output carefully when you enter this command. It will tell you some important information if some updates were not able to populate through the database.
