You are right. I've found the odd thing (that completely drives me
mad) in postgresql.conf.
You are able to reproduce slow-not-in queries by switching
constraint_exclusion to on in your postgresql.conf and running my test
(which is attached to the first message).
Looking forward to hearing from you.
