It wasn' working fine because the wiki_pages table hadn't an id (primary key) field. I've created, in the upgrade process, a temporary table to copy all the wiki_pages records and then, drop and create again the table. Tested under MySQL. Need to be tested (both creation and upgrade) under PostgreSQL!!! Minor modifications to ewikimoodlelib.php to work with this new id field too. Seems to work although deeper tests will be welcome (attachements, binary contents...) Cross your fingers! ;-)
