@Caleb: according to PostgreSQL 8.5devel Docs, no. it won’t fire if you don’t name the column.

in particular, this means that a trigger defined as
CREATE TRIGGER trigger1
BEFORE UPDATE OF column1 ON table1
FOR EACH ROW EXECUTE PROCEDURE trigger1();

will *not* fire when column1 is updated by another trigger.

for me it’s a bit weird but probably it’s standards-compliant, if pg-gods decided this way.

so maybe I’ve read this too fast and it was answered… (I think your code probably answers but…)

Support SQL-compliant triggers on columns, ie fire only if certain columns
are named in the UPDATE’s SET list.

so it won’t fire if I don’t name the column? or just generally do an insert on that column even if I name it?
