{
    // Attributes available to this derive:
    #[inoutfuncs]
    #[pgvarlena_inoutfuncs]
    #[requires]
    #[pgx]
}

Generate necessary bindings for using the type with PostgreSQL.

    treats_received: i64,
    pets_gotten: i64,

• pgvarlena_inoutfuncs(some_in_fn, some_out_fn): Define custom in/out functions for the PgVarlena of this type.
• sql: Same arguments as #[pgx(sql = ..)].
