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.
