We are currently installing Postgresql from the PostgreSQL apt repository. Is there some way to get "apt-get install postgresql-9.6" to use the --data-checksums option when setting up the cluster?

Or do we need to install Postgresql differently?

If you do not want to install and drop the cluster on Debian and related, you could:

  • Install postgresql-common;
  • Edit the /etc/postgresql-common/createcluster.conf file to allow the use of the --data-checksums option;
  • Install postgresql-9.6.

When you use apt-get, it creates a cluster without data checksum. All you have to do is to drop the newly created cluster:

pg_dropcluster 9.6 main

and create a new one with that option

pg_createcluster 9.6 <clusterName> <Youroptions (datachecksum for example)>

Or you can change the file /usr/share/postgresql-common/createcluster.conf to put your data-checksum option there.
