Dear list,

just to answer my question myself by some private help of Herbert:

Here the perfect result to suppress the thickness of the bar that was
that sets all values to the default values and that now allows to
overwrite some globally set pstricks settings easily locally within the
\pspicture environment -- very cool!!!

Herbert, keep as well on trucking on the experimental pstricks-add and
maybe you will move the \resetOptions to the basic pstricks package --
really useful for locally or globally resetting the values to the
default. Indeed this trick solved all my problems to setting values
globally vs. locally.

Yoodle!!!!

\documentclass{article}
\usepackage{pstricks,pst-node}
\usepackage{esvect}
\parindent=0pt
\begin{document}
\psset{arrowscale=4,arrowlength=3,arrowsize=0 1.5,arrowinset=0,
tbarsize=0.25pt 2}
\begin{pspicture}(-0.5,-0.5)(6,3)
\cnode(0,0){0cm}{O}\cnode(4,0){0cm}{A}
\cnode(6,2){0cm}{B}\cnode(2,2){0cm}{C}
\pcline{->}(O)(A)\nbput{$\vv{b}$}
\pcline{->}(O)(C)\naput{$\vv{a}$}
\pcline{->}(A)(B)\nbput{$\vv{a}$}
\pcline{->}(C)(B)\naput{$\vv{b}$}
% Here the trick
\pcline{->}(O)(B)
\resetOptions
\pcline{|-}(O)(B)
% End of the trick
\nbput[nrot=:U]{$\vv{b}+\vv{a}$}
\naput[nrot=:U]{$\vv{a}+\vv{b}$}
\end{pspicture}
\end{document}

Thanks a lot for your steady work and maintainance of the powerful
PSTricks bundle.

Regards,

Juergen
