no, that is not possible. The image is created on PostScript level,
but you need the size on the preceding TeX level. However, you
can use package auto-pst-pdf and run the document with pdflatex
instead:

\documentclass{minimal}
\usepackage[pdf]{pstricks}
\usepackage{pst-node}

\begin{document}
foo
\begin{pspicture}[showgrid](1,1)% incorrect image size
     \pnode(0,3){A}\pnode(4,0){B}\pnode(4,3){C}\psdots(A)(B)(C)
     \psline{->}(A)(B)(C)
\end{pspicture}
bar
\end{document}

imortant is

pdflatex -shell-escape <file>
