Column-level triggers in docs - Mailing list pgsql-docs

I notice that the 9.0 docs page for CREATE TRIGGER doesn't indicate
column-level syntax in the synopsis:
http://www.postgresql.org/docs/9.0/static/sql-createtrigger.html

It does detail the additional syntax required for specifying a column
in the "event" parameter detail, but shouldn't this also be in the
synopsis?

So it would read something like:

CREATE TRIGGER name { BEFORE | AFTER } { event [ OF column_name [, ...
] ] [ OR ... ] }
    ON table [ FOR [ EACH ] { ROW | STATEMENT } ]
    [ WHEN ( condition ) ]
    EXECUTE PROCEDURE function_name ( arguments )
