UPDATE – We have updated our plans for database prefixing and maximum username and database name lengths. For more information, read our latest post: Update to Recent Database Prefixing Post.


This year, we have worked to remove the restrictions on database name length. As of cPanel & WHM version 11.44, you will be able to create:

  • MySQL databases with names that are up to 64 characters long
  • PostgreSQL databases with names that are up to 63 characters long
  • PostgreSQL usernames that are up to 63 characters long

We will also disable database prefixing for new databases and remove the Database Prefixing option from WHM (Home >> SQL Services >> Disable Database Prefix).

New databases that you and your users create will not automatically include a username prefix. However, existing databases and databases that you transfer or restore will retain their username prefixes. You will still have the option to manually add a username prefix in a new database’s name.

Administrators and developers of plugins and other third-party software should plan accordingly.
