In the file /etc/init.d/postgresql-9.4 should be renamed "unix_socket_directory" in "unix_socket_directories" Look http://www.postgresql.org/docs/9.4/static/runtime-config-connection.html unix_socket_directories (string) ... Reproducible: Always Expected Results: ... socket_path=$(get_config unix_socket_directories) ...
this seems to be the same also for 9.3
This changed in 9.3 and nobody noticed for a long time. Most likely due to PostgreSQL being responsible for the socket creation. The fix isn't a simple rename of unix_socket_directory to unix_socket_directories. The initscript will have to support a comma-delimited list of directories that the socket can be created in. So, rather than just checking and/or creating one socket directory, it'll have to be able to do so for multiple directories.
