Trying to plan and get a bit of a jump on 8.3 I see an original project description for Updateable cursors at: http://archives.postgresql.org/pgsql-hackers/2007-01/msg01014.php I'm wondering if there is an updated description somewhere on the site - or better still -- some advice as to whether the PG implementation will pose the same potential penalties as described for Microsoft SQL Server as described at: http://en.wikipedia.org/wiki/Cursor_%28databases%29 towards the bottom of the page (Disadvantages of Cursors). Thanks
