Hello,

In Postgres 9.0, trying to prevent a recursive trigger by adding a column
"notrigger".

Psuedo code: create trigger before_update_holdings_table BEFORE UPDATE ON
holdings FOR EACH ROW when (new.notrigger is not given) EXECUTE PROCEDURE
before_update_holdings();

I see in the docs, I can do the opposite - have it fire only when a field is
included.

1) Is there any way to do the above, have a trigger fire when a field is not
specifically included?
2) If not, what is the easiest way to prevent recursive triggers (in the
update trigger, other update are done to the table and the trigger should be
ignored).

Thanks,
