After running an update on a drupal site, I got the following error when looking at any content: Unknown column 'u.signature_format' in 'field list'.

There was this thread on it http://drupal.org/node/508666#comment-1783504

Someone said that they solved this by running a query. There was no query offered, but I was able to create one quickly by looking at the users install code:

alter table users add column signature_format smallint not null default 0
