Improve type conversion and responses for raw queries

Bug description

I am using prisma.$queryRaw for creating mapbox vector tiles from db using PostgreSQL and PostGIS I expect get node.js Buffer in mvt field but prisma query engine serialize the db response to text and I can’t correctly convert it to a buffer

Buffer.from(data.mvt as string, 'binary')

is not help!

How to reproduce

Expected behavior

prism should return a Buffer in place of text for binary data

Example:

let r#type = match &p_value {
    quaint::Value::Integer(_) => "integer",
    quaint::Value::Float(_) => "float",
    quaint::Value::Double(_) => "double",
    quaint::Value::Text(_) => "text",
    quaint::Value::Enum(_) => "enum",
    quaint::Value::Bytes(_) => "bytes",
    quaint::Value::Boolean(_) => "bool",
    quaint::Value::Char(_) => "char",
    quaint::Value::Array(_) => todo!(),
    quaint::Value::Numeric(_) => "numeric",
    quaint::Value::Json(_) => "json",
    quaint::Value::Xml(_) => "xml",
    quaint::Value::Uuid(_) => "uuid",
    quaint::Value::DateTime(_) => "datetime",
    quaint::Value::Date(_) => "date",
    quaint::Value::Time(_) => "time",
};
inner_object.insert(r#type.into(), Value::from(p_value));
object.insert(column_name, Value::Object(inner_object));

You get the point.

Sorry to barge in. But I have exact the same issue using $queryRaw.

I’m using ulid to generate my ids.

https://www.npmjs.com/package/ulid

My table:

model anki_lists {
id         Bytes        @id @db.Binary(26)
name       String?      @db.VarChar(255)
created_at DateTime?    @db.Timestamp(0)
updated_at DateTime?    @db.Timestamp(0)
deleted_at DateTime?    @db.Timestamp(0)
anki_cards anki_cards[]
}

I expect to get back something like:

+----------------------------+------------+
| id                         | name       |
+----------------------------+------------+
| 01esy4337ym3yknze675g3grhy | Pimsleur 1 |
| 01et07hamgxc9e92e72mq78wph | Pimsleur 2 |
+----------------------------+------------+
2 rows in set (0.023 sec)

Except when I console log the result of the raw query:

[
{ id: 'MDFlc3k0MzM3eW0zeWtuemU2NzVnM2dyaHk=', name: 'Pimsleur 1' },
{ id: 'MDFldDA3aGFtZ3hjOWU5MmU3Mm1xNzh3cGg=', name: 'Pimsleur 2' }
]

I should be receiving a buffer instead of an encoded string?

Let me know what you need to solve this issue.

Thanks
