The server does not support that, but if you're running a script
through psql you should look at using:

\set ON_ERROR_ROLLBACK on

Docs at:

http://www.postgresql.org/docs/9.3/interactive/app-psql.html

If you are not using psql you can use savepoints:

http://www.postgresql.org/docs/8.4/interactive/sql-savepoint.html

ROLLBACK TO SAVEPOINT if the statement fails.
