- Bug-fix: Make sure, trigger content_item_search__utrg does try to delete content from via search queue when old publish_date was in the future (since this is avoided by the same trigger). (Oracle seems to implement search quite different)
- Add argument to content_item__set_live_revision (and oracle's counterpart) to honor optionally provided "publish_date". The old behavior used hard-coded the current time. The function is fully backward compatible, when no publish_date is provided, the current time is used for the publish_date. - changes for PostgreSQL and Oracle.
