Enum CastOperation 

pub enum CastOperation {
    Create {
        cast: Box<Cast>,
    },
    Drop {
        identifier: CastIdentifier,
    },
    Replace {
        old_cast: Box<Cast>,
        new_cast: Box<Cast>,
    },
}

Operations that can be performed on casts.

PostgreSQL has no ALTER CAST, so any structural change is a DROP + CREATE (Replace). Only the comment can be altered without a recreate.
