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
