I think inverting the vacuum and analyze frequency is wrong.
Me. Too. ATM all I can think of this patch attached. Josh, is it sufficient
for you?..:-)
The patch just adds an example to the README, this looks ok to me.
Matthew, I am confyused about one thing. Why would autovacuum count updates
while checking for analyze threshold? Analyze does not change statistics
right? ( w.r.t line 1072, pg_autovacuum.c). For updating statistics, only
inserts+deletes should suffice, isn't it?
An update is the equivelant of an insert and a delete, so it counts
towards the analyze count as much as an insert.
Other than that, I think autovacuum does everything it can.
It could be more customizable.
