What happened?
Support for nullable columns in joins were added in v1.9.0. Unfortunately, it appears this doesn't extend to the auto-generated enum types. As can be seen in the generated Go types, the ListBooksRow contains an sql.NullString, but the enum type is not similarly nullable.
There's a bit of a design discussion to be had around what the best way to handle this is, since enums use a custom type. Perhaps a pointer would be enough, so that it could be null?
