[Typo3-dev] System Extensions, part II

[Kasper Skårhøj]

The problem is that when versions are swapped the introduction of a
temporary negative uid will set the internal "next autoindex" to some 2
billions.

A fix CAN be made which simply performs these steps after a version
swap:
- Lookup the highest uid (or record the previous next autoindex)
- issue an "ALTER TABLE" command which sets the next autoindex.

Of course this is a hack that requires that we can get a hold of the
MySQL version number - if MySQL is the database (... DBAL...)
