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

    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

Catch ex As Exception
End Try

Unfortunateky I don't know when the official libpq version will implement the functionalities which      
the REL_07_03_ENHANCED already has.

REL-07_03_ENHANCED works correctly.  I have not properly 
understood whether the functions of this version will be 
present in the official release or if they belong to two 
different projects

REL-07_03_ENHANCED version has an option to avoid the impicit rollback. Please try it.
