Hi,
readding around I just found this:
The CREATE TRIGGER statement in PostgreSQL implements a subset of the
SQL99 standard. (There are no provisions for triggers in SQL92.) The
following functionality IS MISSING:
* SQL99 allows triggers to fire on updates to specific columns (e.g.,
AFTER UPDATE OF col1, col2).
* .....
Does anybody know if that's true on version postgresql (PostgreSQL)
8.1.2? Because I don't actually know from what version that sentence is.
Yes it is true for the current version.
Up-to-date documentation always ships with a release and is also
available on the website.
