-  <para>
-   <command>SET CONSTRAINTS</command> sets the behavior of constraint
-   evaluation in the current transaction. In
-   <option>IMMEDIATE</option> mode, constraints are checked at the end
-   of each statement. In <option>DEFERRED</option> mode, constraints
-   are not checked until transaction commit.
-  </para>
-
-  <para>
-   Upon creation, a constraint is always give one of three
-   characteristics: <option>INITIALLY DEFERRED</option>,
-   <option>INITIALLY IMMEDIATE DEFERRABLE</option>, or
-   <option>INITIALLY IMMEDIATE NOT DEFERRABLE</option>. The third
-   class is not affected by the <command>SET CONSTRAINTS</command>
-   command.
-  </para>
-
-  <para>
-   Currently, only foreign key constraints are affected by this
-   setting. Check and unique constraints are always effectively
-   initially immediate not deferrable.
