[ref 14] PostgreSQL doesnŐt follow the SQL standard when you create two <tt>SAVEPOINT</tt>s within the same transaction.  PostgreSQL simply hides the old <tt>SAVEPOINT</tt>&#151;the SQL standard states that the old <tt>SAVEPOINT</tt> should be destroyed. If you need the SQL-prescribed behavior, you can destroy the old <tt>SAVEPOINT</tt> with the command <tt>RELEASE SAVEPOINT <em>savepoint-name</em></tt>.
