Summary: Rollback in manual transaction

Initial Comment:
Postgres 8.1 either Windows or linux
psqlODBC 08.01.0200
..Net Framework 1.1 in particular Visual Basic

In Notes: psqlODBC 08.01.0106 I read:
....
3) doesn't call rollback in autocommit off or in manual transaction
....

But Executing a statement in a transaction which gives an error causes an implicit rollback of the transaction and the close of the connection.
Sample code:

Dim cnt As New Odbc.OdbcConnection"Driver={PostgreSQL Unicode}; Server=****; Database=test_ado; Uid=postgres; Password=****; BoolsAsChar=0; Parse=0; UniqueIndex=1; TextAsLongVarchar=1; LowerCaseIdentifier=1")
Dim tra As Odbc.OdbcTransaction
Dim sSql As String

Try
cnt.Open()
tra = cnt.BeginTransaction()
'Setting Primary key to Null cause an error
sSql = "UPDATE test_ado SET cod=Null WHERE cod ='00004'"
Dim cmd As New Odbc.OdbcCommand(sSql, cnt)
cmd.CommandText = sSql
cmd.Transaction = tra
cmd.ExecuteNonQuery()

Catch ex As Exception
MsgBox(ex.Message)
MsgBox(cnt.State.ToString)
End Try
