FtsContentProvider etp_page_revision etp_page_revision edit-this-page Uninstall
If not you have to manually run packages/edit-this-page/sql/postgresql/edit-this-page-sc-create.sql which is not run automatically upon installation for some reason. Restart aolserver. (Always restart when dealing with service contracts to be on the safe side).
Unfortunately the search_indexer doesn't complain when there is no service contract installed for an object type but it simply discards the entries. So after you installed the bindings you'll have to reinsert the content in the queue and wait for (or manually run, e.g. from the very useful acs-developer-support shell at /ds/shell/) the search_indexer.
