Issue status update for http://drupal.org/node/27108 Post a follow up: http://drupal.org/project/comments/add/27108 Project: Drupal Version: 4.6.2 Component: book.module Category: bug reports Priority: normal Assigned to: Anonymous Reported by: Daniel Lyons Updated by: Daniel Lyons Status: patch Attachment: http://drupal.org/files/issues/book.module_4.patch (2.71 KB) Hi, I'm running Drupal on PostgreSQL 8.0.1 and had to modify the book module a little bit to make it work on my system. It's pretty minor--you just have to ensure that you are also SELECTing all the columns you're using in your ORDER BY expression, otherwise PostgreSQL will reject the query. These changes should have zero ramifications for MySQL installations. Here is a patch against 4.6.2 which makes these changes. Daniel Lyons
