ODBC & Transactions?

Hi,

I'm having a little bit of trouble with transactions.
I'm using psqlodbc-07.01.0008; PostgreSQL 7.1.2 on i686-pc-linux-gnu,
compiled by GCC 2.95.3; VB 6 SP5 with ADO (MDAC 2.6 SP1)

If I execute the SQL statements using ADO in VB6:

begin work
update mytable set myfield='changed-data' where myid = 1
rollback work

and then I check the database using psql on the server box, myfield =
'changed-data'; and the rollback did *not* work.

In the postgres log appears:
NOTICE: ROLLBACK: no transaction in progress

I've attached a psqlodbc log file (if attachments are allowed - it should
appear)

Are transactions supported in postgresql ODBC?

(I've tried adoConnection.BeginTrans; etc as well with no success)

Any help appreciated.
