Get this result back when putting `postgres -D /usr/local/var/postgres` in terminal

Question

When I put postgres -D /usr/local/var/postgres in terminal I get this back:

LOG: could not translate host name "localhost", service "5432" to address: nodename nor servname provided, or not known
WARNING: could not create listen socket for "localhost"
FATAL: could not create any TCP/IP sockets`

Can someone help me fix this?

Check your /etc/hosts file for missing line:

127.0.0.1 localhost.localdomain localhost
