There was just a thread along these lines in -performance. *If*
performance becomes a concern, you can replace that update with:
insert into queue_table
Then periodically delete from that table using a plpgsql function that
can catch a row count, and use that row count to update your views
table.
But remember the first rule of performance tuning: don't.
