Well, the main problem is the confusion a failure causes. How
should a user decide whether he can run the database safely or
not, after a failed regression test? Or even what the reason
for failure was?
FastFPE on ARM is expected and seems to belong to "dont worry"
category. And I dont like saying: "Couple of regression failures
are normal".
Although I can understand that 'reduced precision' may sound
worrysome to lot of people. Maybe there should be new class
of failures in pg_regress: "expected failures" - which still
count as failures but have little note explaining the problem
so user can decide about the severity.
