Operating system: Windows
Description: Driver issue
Details:

I am using Driver = PostgreSQL UNICODE.
I am retrieving the dataset using this connection string.

I am using .Net application.
when i try to user OdbcDataAdapter and fill the dataset its failing.

code snippet:
OdbcDataAdapter odbcAdapt = new OdbcDataAdapter("Select * from
table1;"+"Select * from Table2", connection);

odbcAdapt.Fill(dataset);

dataSet.Count is 0.

If I use Driver = postgres instead of Postgres Unicode. this is working.
