Can users be assigned privileges to a certain number of MySQL databases and a different number of PostgreSQL databases ?

You can set the maximum number of total databases that user can create with packages, as well as when creating accounts without packages.

If you set a limit for databases, this will allow that limit for each type. So right now, you can offer:

• X MySQL, or
• X PostgreSQL, or
• X MySQL and X PostgreSQL.

In the future, you will be able to offer X PostgreSQL and Y MySQL.
