I think you're right about "SET AUTOCOMMIT TO OFF" being removed from 7.4. 
In any case, what you want to is use transactions. I think the confusion 
occurs because in some (many?) client-side languages you inititiate a 
transaction by setting auto-commit to off (JDBC and ODBC do this) in the 
client-side driver. In the case of the PostgreSQL JDBC driver, this causes 
a BEGIN command to be sent to the server. I would imagine ODBC does the 
same.
