- removal of forums_reading_info_user (1Mio rows on Learn@WU). This materialized view had to be constantly synced with forums_reading_info table. Reimplemented as view. - simplify logics in stored procedure due to new datamodel - fix inconsistencies between oracle and postgres function definition - re-enabled parameter to decide whether use these stats or not in administration
TODO: consider further reform of this feature as stats grow very large on busy sites for probably little value added
