text), and I create a view:
create view v as
select a.adate, a.aval, b.bval from a join b o

Hi!
I am trying to solve the problem of estimating the table bloat (and index
bloat, though I am mostly focusing on tables at the moment).
After searching far and wide, it seems that the choice is to be made
between two methods:
1. Slow, but very precise pgstattuple
2. Fast, but somewhat imprecis
