Description

Using the core cache for schema information comes with
various drawbacks.
1. There is no way to flush single core cache entries,
thus the complete core cache needs to be flushed when
changing the database schema
2. The PHP Frontend provides no benefit, when the to be cached
information has to be serialized anyway.

Last but not least, currently not only the core cache, but ALL caches
are flushed after schema updates, which leads to errors, when some cache tables
are not created during one schema update.
