I am interested in how hibernate.hbm2ddl.auto=validate actually works and I am struggling to find comprehensive documentation.

We've recently discovered production system was affected by http://opensource.atlassian.com/projects/hibernate/browse/HHH-3532 (Hibernate matches foreign keys on name, rather than signature and so will recreate them for you) and hibernate.hbm2ddl.auto=update is being removed from our next release.

I would be quite happy to just get rid of hibernate.hbm2ddl.auto altogether and manage our database ourselves. However, not all my colleagues share this world view and some are keen to add back in hibernate.hbm2ddl.auto=validate.

I'm concerned this will hit the same problem and I'm interested in finding more documentation about how this validation actually works. The Hibernate Community Documentation (http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html) really just makes reference to the values.

Does anyone have any good documentation pointers, or any real life experience of using validate in a production system?
