It should be mentioned, that there is a Begin; in PostgreSQL, that also initiates a transaction block, which at first confused me.

http://www.postgresql.org/docs/9.0/static/sql-begin.html

"BEGIN initiates a transaction block, that is, all statements after a BEGIN command will be executed in a single transaction until an explicit COMMIT or ROLLBACK is given. By default (without BEGIN), PostgreSQL executes transactions in "autocommit" mode, that is, each statement is executed in its own transaction and a commit is implicitly performed at the end of the statement (if execution was successful, otherwise a rollback is done)."
