this is completely wrong - you never change user data. This is not a schema update

Then tell it those who have created that schema update, that was not me. I only say as long as we can change it, i.e. before beta, we should change it so it is consistent with joomla.sql. Anyway I will close discussion.

The database schema of a database system is its structure described in a formal language supported by the database management system. The term "schema" refers to the organization of data as a blueprint of how the database is constructed

nothing to do with content

Then call it update sql abused for content updates. All I said is change it as long as we can. And there is no need to explain me what a schema is.
