Hi Kiorky.

Sorry for late response...
I was in a conference here in my country and couldn't answer you in time :)

I'm at my job right now and I don't have the complete devel environment 
setup here...
I will try your example when I get home to see if I get the same results...


I see that you are passing the delete, inserts and select to dataadapter...
could you try to send the delete and inserts first, with 
NpgsqlCommand.ExecuteNonQuery() and later try to use the dataadapter 
with select only?

I hope it helps.

Regards,
