[GENERAL] Dynamic triggers

[Rob Richardson]

Sid posted a link to a Wiki example of a dynamic trigger:
http://wiki.postgresql.org/wiki/PL/pgSQL_Dynamic_Triggers
<http://wiki.postgresql.org/wiki/PL/pgSQL_Dynamic_Triggers> .  The link
shows a trigger, but it doesn't say anything about what its purpose is
or what a dynamic trigger is supposed to be good for.  What is it good
for?
 
Thank you!
