The vacuum extension adds an additional changelog tag/command to support vacuuming. As of version 1.0, it only supports database-level vacuuming. Future versions will include table-level config as well as support for controlling vacuum options. Note: vacuum cannot run in a transaction, so specify runInTransaction="false" in the containing changeSet.
There is currently no dedicated .xsd file file those using an XML-based change log. Therefore, use the standard extension xsd of http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd.
