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.
