I'm a little doubtful about whether this particular thing is generally useful but I think the bar for adding a field to PgStat_StatDBEntry is probably a lot lower than for a per-table counter. I think adding table-level counters is basically not happening without some kind of rework of the infrastructure; whereas adding db-level counters seems like it might be OK if we were convinced that they had real value. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
