I don't have a strong opinion, but I lean towards having them on
by default. Yes, that has a performance impact (e.g. WAL logging hints),
and people with reliable storage may be better off disabling checksums.
But I think it is better to set the default values so that they are
good for those people who don't have a lot of PostgreSQL knowledge and
are running less demanding installations on mediocre hardware.
