[postgresql] postgresql-setup: handle --version option earlier

    postgresql-setup: handle --version option earlier
    
    This generated the manual page badly before as the output of
    --version option depended on system's postgresql.service (not
    available at a build time).  So handle options rather at the
    beginning of the script.
    
    Version: 9.3.2-5
