very nicely done!
HOWTO's done in this way are fantastic for the community, could tikibot search for HOWTO ? Maybe we can use the WIKI farm for that once its completed.
i get SQL errors from the Workflow items.
Is this known or is it a bug?
There's no real point in having the page text in the indicies. The indicies mostly help PostGres with matching values to the table. I doubt that anyone will be searching the table for the entire page text, so why not just remove the page text from the indicies? That's what I did to get around this problem.
