What is the current status of FOR UPDATE cursors ?

What is the current status of FOR UPDATE cursors ?

older docs claim that the syntax is supported, but gives an error

http://www.postgresql.org/docs/8.2/static/sql-declare.html

docs for 9.1 do not have FOR UPDATE in main section

http://www.postgresql.org/docs/9.1/static/sql-declare.html

but then discuss using for update cursors further down.
