Currently, version_id is generated from txid_current(), which is not portable between database installations. As a result, it's not possible to simply dump data from one server to another, because the version ID generation may conflict.
One way to around this issue would be to add a database_version_id, which would be incremented upon a database migration. SavageLogMixin would need to add a database_version_id column, and there would need to be a separate DatabaseVersionId table with a single value (which defaults to 0/1).
