I downloaded postgres app and when I create new server on port 5432 try to start it I get an error:

pg_ctl: could not start server

Answer 1

The permissions on your /tmp are messed up. They should be so that everybody could create files there:

$ ls -ld /tmp
drwxrwxrwt 24 root root 620 Sep 26 07:26 /tmp

I would reinstall the operating system and start again.
