use diesel::sqlite::pragma::{AutoVacuum, SchemaPragma};

let conn = &mut SqliteConnection::establish(":memory:").unwrap();
assert_eq!(AutoVacuumMode::None, AutoVacuum::get::<AutoVacuumMode>(None, conn)?);
AutoVacuum::set(AutoVacuumMode::Incremental, None, conn)?;
assert_eq!(
    AutoVacuumMode::Incremental,
    AutoVacuum::get::<AutoVacuumMode>(None, conn)?
