missing transient dependency?
These two functions are run in seq, DB wraps sql.DB. The result is the following output
INFO[0000] Connecting to postgres://postgres:postgres@localhost:7883/myservice?sslmode=disable
INFO[0000] Connection SUCCESS

Solved, needed import
_ "github.com/mattes/migrate/source/file"
The documentation in the main readme reads:
Migration Sources
Source drivers read migrations from local or remote sources. Add a new source?
Filesystem - read from fileystem (always included)
Maybe before closing this you should fix the documentation that caused it in the first place....
