I can, very easily.  It happens whenever we stand up a new server, dump
our tables into it, create our UNION ALL views, and then try to query
them.  Sure, we've gotten used to "oh, we need to go check and make sure
constraint_exclusion is on", but it can be annoying, and if we're ever
handing off our table structures/setups to other people we have to
remember to tell them "oh, and don't forget to enable
constraint_exclusion!", etc, etc..
