WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.
Success. You can now start the database server using:
    /usr/bin/postgres -D /var/lib/postgres/data
or
    /usr/bin/pg_ctl -D /var/lib/postgres/data -l logfile start
:: Starting PostgreSQL                                                   [DONE] 

postgres does not know where to find the server configuration file.
You must specify the --config-file or -D invocation option or set the PGDATA environment variable.

sudo  /usr/bin/postgres -D /var/lib/postgres/data

"root" execution of the PostgreSQL server is not permitted.
The server must be started under an unprivileged user ID to prevent
possible system security compromise.  See the documentation for
more information on how to properly start the server.
