Stream seek error

Hi all!

Since Npgsql RC1, we started to receive some error reports about problems when closing connections. The typical stack trace looked like this:

System.NotSupportedException : This stream does not support seek operations.

at System.Net.Sockets.NetworkStream.Seek(Int64 offset, SeekOrigin origin)

at System.IO.BufferedStream.FlushRead()
at System.IO.BufferedStream.WriteByte(Byte value)

This seems to be caused by some out of sync problem with Npgsql. I proposed a solution in our bug tracking about this problem.

Please, give it a try and let me know if it solves the problem.

Thanks in advance.
