PgsqlCommand.ExecuteReader() throws InvalidOperationException when not connected to the server

Hi,

I am just evaluating this product. Probably I will buy it.
I have found a bug in the datareader sample: PgsqlCommand.ExecuteReader() throws an InvalidOperationException when not connected to the server. It says that the connection must be opened. I think this should be handled by the library. It seems a socket error.
The exception is thrown in Common:Util:a(...).

Regards,
Szinkopa

This exception is raised by PostgreSQLDirect .NET if you call ExecuteReader() with closed connection.
You must open connection before calling ExecuteReader() method.

Ok, thanks. Is there any way to get to know what exceptions this library may throw?
