Hi, I'm using multiples versions of PostgreSQL from the postgresql.org repository (http://apt.postgresql.org/) on Debian Jessie, on multiples servers. Each postgresql-client-XX package depends on postgresql-client-common, which provides the pg_wrapper script (/usr/share/postgresql-common/pg_wrapper). A lot of PostgreSQL commands are linked to pg_wrapper. E.g.: /usr/bin/psql -> ../share/postgresql-common/pg_wrapper Here's my issue : when I'm logged as an user which is not root or postgresql, I can't use any of the commands linked to pg_wrapper: user1@server1:~ $ /usr/bin/psql --version Error: Invalid data directory However, everything works with postgres or root user: root@server1:~ # /usr/bin/psql --version psql (PostgreSQL) 9.4.16 Also, everything works fine if I bypass pg_wrapper: user1@server1:~ $ /usr/lib/postgresql/9.4/bin/psql --version psql (PostgreSQL) 9.4.16 I am missing something ? Thanks, -- Jonathan Leroy
