replace('www.', '').replace('.', '_')

I saw you delete www and dots from database name.

Is it really needed? It seems, that you have to do it in many places of code.
Maybe we can keep database name as is.

Nginx can delete "www." before redirecting to odoo.

To allow dots in new database that is created from /web/database/manager you can apply patch as follows:
sed -i 's/matches="[^"]*"//g' addons/web/static/src/xml/base.xml

Actually, now I'm removing www in Nginx configuration as you say. So, we can delete that replace.

I will check the using of '_' instead '.' in the code before fix it just in saas_utils.
