Hi,
It looks like this commit:
<http://archives.postgresql.org/pgsql-committers/2009-12/msg00313.php>
implemented a working version of
information_schema.triggered_update_columns, but left in the comment
stating:
-- PostgreSQL doesn't allow the specification of individual triggered
-- update columns, so this view is empty.
I think this comment should be removed, as it's no longer accurate.
Patch attached.
Josh
