IMO the naming of autocommit is all but a good one. 

There is only one way to commit a transaction in ecpg and that's by issuing
a COMMIT resp. END WORK statement. The only difference between the two ways
of operation in ecpg is how to start a transaction.

With AUTOCOMMIT set to ON a transaction is started only via a BEGIN WORK
statement. Ot in other words if you do not start a transaction each
statement is its own one and thus autocommitted. If AUTOCOMMIT is set to OFF
ecpg always starts a new transaction after a COMMIT resp. a ROLLBACK.

Yes, this looks like there is no commit after the create and AUTOCOMMIT is
set to OFF (default).
