Which indeed is correct. "Autocommit" means that the mode is the same as
with for instance psql. Each statement is run inside its own transaction
and thus you do only need a "commit" if you specified a "begin" before.
Without "autocommit" the mode is equivalent to Oracle in that an
explicit transaction is started automatically and all you need to do is
issue a "commit" or "rollback" to end. After that a new transaction is
started immediately.

Yes, that's it. No need to say "begin" when not using "-t".
