To take this a step further, if you really have a lot of tables and want to do it automatically, you could do something like this:

SELECT table_name,add_trigger(table_name) FROM information_schema.tables WHERE table_schema='public';

This assumes that you want to add the trigger to _all_ your tables, and that you haven't made use of schemas and so your tables are all in the public schema. 

If that's not the case, you could adjust accordingly.  It would be safest to just pull the table names first, make sure the list is what you want, and then run with the add_trigger.  So start with this:

SELECT table_name FROM information_schema.tables WHERE table_schema='public';

and if the list of tables is what you want, then run with the add_trigger included.

Cheers,

Ken
