Meu servidor PostgreSQL 9.5 no Debian 8 (Jessie) continua saindo diretamente após ser iniciado via service postgresql start :
# service postgresql status
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled)
Active: active (exited) since Fr 2016-12-02 11:02:51 CET; 11min ago

Dez 05 16:29:24 dev systemd[1]: Starting PostgreSQL RDBMS...
Dez 05 16:29:24 dev systemd[1]: Started PostgreSQL RDBMS.
Observe o estado active (exited) . O servidor está inoperante, por exemplo Não consigo me conectar a ele via TCP ou soquete de domínio, e não consigo encontrar nenhum processo associado.
No entanto, quando eu inicio o PostgreSQL manualmente ele funciona:
# sudo -u postgres /usr/lib/postgresql/9.5/bin/postgres -d 3 -D /var/lib/postgresql/9.5/main/ -c config_file=/etc/postgresql/9.5/main/postgresql.conf

No caso de uma execução malsucedida via service postgresql start , nenhum log é gravado em% para /var/log/postgresql . Da mesma forma, não consigo encontrar nenhuma mensagem relacionada ao PostgreSQL em /var/log/messages .
Eu instalei o PostgreSQL através do repositório oficial:
