func DBVersion ¶

func DBVersion(db queryExecutor) (uint64, error)

DBVersion returns the current version of the database schema. The library exposes a GetDBVersion function which however requires a *sql.Db object. Several contest flows work instead within a transactional context, so we need to be able to extract the version in a way that is agnostic to the `sql` object used (either `sql.Tx` or `sql.Db`).
