This adds the pp_sortkey column to the page_props table. pp_sortkeys allows for top-k queries for pages, e.g. the 100 pages with the most language links, etc. It is also possible to query for exact values. For now, pp_sortkey will contain pp_value's numeric value if the value was set to a float, int or boolean. Associated tasks: * create a maintenance script for populating pp_sortkey. Tricky, because when reading from the database, all values are strings. * create an API module for querying pages by property value. bug: 58032 Change-Id: I217c42656fb877ff35a36eb446a22bdaf119faac
