OK, I've found the issue : pg_wrapper is trying to get the value of the "data_directory" setting by reading the postgresql.conf file. However, my user can't access the postgresql.conf file. So I've bootstrapped a fresh Debian 8 VM with just postgresql-9.6, and compared files permissions between that VM and my production servers. All my production postgresql.conf files have a chmod 640 vs 644 on my new VM. After digging, I've found that the SaltStack recipe who configure all my servers force the file chmod to 640... I've fixed it: everything works now. :) Thank you all for your help! -- Jonathan Leroy
