coverage appears low but in reality all the main parts are covered.
This is a database based package. I use a fake database driver designed for testing (https://github.com/DATA-DOG/go-sqlmock), but it doesn't return the data types of each column (which a normal database driver would). Therefore that portion of the code is not covered.
