<para>
An event trigger fires whenever the event with which it is associated
occurs in the database in which it is defined. Currently, the only
- supported event is <literal>ddl_command_start</>. Support for
- additional events may be added in future releases.
+ supported events are <literal>ddl_command_start</>
+ and <literal>ddl_command_end</>. Support for additional events may be
+ added in future releases.
</para>
<para>
<literal>CREATE TABLE AS</literal>.
</para>
+ <para>
+ The <literal>ddl_command_end</> event occurs just before returning
+ control from the execution of a <literal>CREATE</>, <literal>ALTER</>,
+ or <literal>DROP</> commmand. It shares the same exceptions as
+ the <literal>ddl_command_start</> event.
+ </para>
