Hi, I'm updating my database from 9.4 to 9.6 (Debian Jessie to Stretch). I think that it is a good opportunity to turn on data checksum. I don't have experience with cluster creation or moving a DB to a new cluster. I'll use pg_upgradecluster, but I don't see any option to turn of data checksum. I took a look to the pg_upgradecluster script. I think that it invokes pg_createcluster. Therefore I think that I should get data checksums if I add in the file /etc/postgresql-common/createcluster.conf the following line: initdb_options = '--data-checksums' Is this correct?
