In want to store an array in this field. [Field] public byte[] SerializedTaskPackage { get; private set; } And i get completely wrong array back (double size +1 )

It is a PostgreSQL specific problem, memory provider and sqlserver provider work. I use PostgreSQL 9.0.2 64-bit

After some research i found that the delivered data is ASCII encoded with a "\" at the beginning and two ASCII Hex Digits'0'-'9', 'a'-'f' for each byte:

byte[0]; -> {92}  "\"
{0} -> {92,48,48} "\00"
{0,1} -> {92,48,48,48,49} "\0001"

Here is the test code:

[Serializable]
[HierarchyRoot]
public class BlobEntity : Entity
    {
        [Field, Key]
        public int Id { get; private set; }

        [Field]
        public byte[] BlobData { get; set; }
    }

    static void Main(string[] args)
    {
        // var config = new DomainConfiguration("memory://localhost/DO40-Tests");
        // var config = new DomainConfiguration("sqlserver://localhost\\SQLExpress/do4test");
        var config = new DomainConfiguration("postgresql://do4test:do4test@localhost:5433/do4test");
        config.UpgradeMode = DomainUpgradeMode.Recreate;
        config.Types.Register(typeof(BlobEntity).Assembly, typeof(BlobEntity).Namespace);
        Domain domain = Domain.Build(config);

        using (Session.Open((Domain)domain))
        {
            using (var transactionScope = Transaction.Open())
            {
                var blob = new BlobEntity();

                blob.BlobData = new byte[] {0,1};

                transactionScope.Complete();
            }
        }

        using (Session.Open((Domain)domain))
        {
            using (var transactionScope = Transaction.Open())
            {
                foreach (BlobEntity blob in (from blob in Query.All<BlobEntity>() select blob ))
                {
                    var blobData = blob.BlobData;

                }
                transactionScope.Complete();
            }
        }
    }
