I'm using Fedora Core 1 with "postgresql-server-7.3.4-11" installed from RPM
and Npgsql (from Mono/CVS) doesn't work for me (while it used to work
properly about one month ago).

I get "System.NullReferenceException : Object reference not set to an
instance of an object" when connecting. The problem seems to occur in

I've made the following patch to this function.

             if (BackendProtocolVersion == ProtocolVersion.Version2)

and it prints "_serverVersion is null". It obviously fails on
_serverVersion.IndexOf() right after that.

My ConnectionString is:

'Server=fw.home.lan;Initial Catalog=SoodaUnitTests;User

I can provide more debug info but I don't know what exactly is needed here.
Any ideas?
