the elements of the array are numbers. The reason why you need
the commented line:

\documentclass[a4paper,14pt]{article}
\usepackage[x11names]{xcolor}
\usepackage{pstricks-add}

\begin{filecontents}[noheader,force]{hubble.txt}
     1.1
     1.2
     1.3
     1.4
\end{filecontents}

\begin{document}
     ~
     \pstverb{/Times-Roman findfont 12 scalefont setfont
         /hubblearray [ (hubble.txt)  run ]  def
         hubblearray 1 get 20 string cvs show
         100 0 moveto
         (Hello!) show
         100 10 moveto
         100 2 neg moveto
         130 2 neg lineto stroke
         showpage
     }
\end{document}
