It's still there, just further down:

  * In to_timestamp and to_date, weekday names or numbers (DAY, D, and
    related field types) are accepted but are ignored for purposes of
    computing the result. The same is true for quarter (Q) fields.

I think this was changed because we noticed that the docs failed to point
out the issue for weekday fields, and cramming similar annotations into
their already-long table entries didn't make sense.  So the info got moved
to the commentary below.
