Could you please provide a valid query to get row count for > all db tables in psql 7.4.3 ? The documentation of 7.4 does not mention explicitely what are the columns of this view, but connecting to a 7.4 server and issuing "¥d pg_stat_user_tables" would help and you might be able to get an equivalent of what you are trying to do. -- Michael
