Seq Scan on organizations o (cost=0.00..4.21 ***rows=1*** width=37)
Filter: (id = id)
On a PG11 instance with the same or very very similar data, I get-
Seq Scan on organizations o (cost=0.00..5.70 ***rows=270*** width=37) Filter: (id IS NOT NULL)
Given this is a not null field, it translates to "is true" basically. The real query that this example was extracted from apparently had a typo in the join resulting in this bogus id = id condition, but I still curious about where this estimate change comes from.
