[Mono-devel-list] Problem with DbDataAdapter...

[Konstantin Triger]

Hello Hubert,

There was a change during this week end: the Mainsoft changes were 
merged into the trunk (they were previously available at 
Mainsoft.System.Data branch).

 From the stack I suppose that PG provider does not fully initialize the 
SchemaTable and some columns contain nulls.

Let me know whether the attached patch fixes the problem and I'll check 
it in.

Regards,
Konstantin Triger
