[important]
I use IDbCommand than NpgsqlCommand.=20

[code sample (not runable, only FYI)]
Int64 id =3D 100;
...
IDbCommand cmd =3D conn.CreateCommand();
NpgsqlParameter pkParameter =3D new NpgsqlParameter("id",
NpgsqlDbType.Bigint);
...
cmd.Parameters.Add(pkParameter);
...
cmd.Parameters[0] =3D id;// throw exception here.
