Hi,
I ran into the same thing last week. There is no way to specify that
functionality in the trigger creation for Postgresql. You will have to code
the trigger to detect when the specific field is updated. Tom Lane had
suggested something for me last week. Check out the archive for the mailing
list at
http://archives.postgresql.org/pgsql-sql/2003-11/index.php
and scroll down to November 26. Perhaps Tom will have more to say on this,
he's pretty good at this stuff.
On another note have you converted any instead of triggers from Oracle to
Postgres? I'm not sure how to do that yet, maybe using rules but I'll save
that for another message to the mailing list.

Hello
I've got a problem in porting a trigger from Oracle into PostgreSQL. In
Oracle you can choose between UPDATE and UPDATE OF COLUMN ...
Is there a way to have the same functionality in PostgreSQL?
Hope anyone can give me an advice.
Doris
