 1) Add the field or table in the ispconfig3.sql file. This file contains the
    complete database dump which is used when ISPConfig gets installed.

-   table, or if it is a complete new table then the add table, statement(s) in 
-   MySQL syntax which is/are required to modify the current ispconfig database

-   you choose for the new file is a +1 increment of the number of the last
-   existing file and that the number is formatted with 4 digits.

-   A patch file may contain one or more alter table statements. Every patch file
-   gets executed once in the database, so do not modify older (already released) 
-   patch files, they will not get executed again if the update was already run 
-   once on a system.
+   Please do not create new patch sql files as those will be generated on
+   new releases from the upd_dev_collection.sql file. Also please do not
+   modify older (already released) patch files, they will not get executed
+   again if the update was already run once on a system.
 
    After a patch has been executed, the dbversion field in the server table gets
    increeased to the version number of the last installed patch.
