Actually most of the estimates seem pretty good. There are some that
are a ways off, but the real nasties seem to be these. I'm a bit
confused because it looks like two of your joins don't have Join
Filters -- and one of those is a left join for which I thought that
was impossible.
Are you sure this query is doing what you expect? You have
add_missing_from enabled which will happily bring in additional joins
if you reference a table which isn't already included in the join and
do a full cartesian-product join.
