There is some common known bugs in 08.01.0102 in implicit rollback.
Do you try latest development snapshot?
Maybe 08.01.0106 could better fit you. I don't know. We have some report
about similar problem (but reporter doesn't mentioned his psqlodbc version).

In this case you may call BEGIN (START TRANSACTION is supported since
08.01.0107).

Yes you do ... When you use autocommit = off you have to start and end
transaction manually. There is hack in psqlodbc which start transaction
automatically even in autocommit = off when you use select, insert, update
or delete SQL statement.

What about try the latest development snapshot as I mentioned above?
