for latex it is a tabular which is always vertically centered
to the current baseline, but for ps4pdf the psframebox is a
grafic with its lower side on the baseline.
This should help:

\documentclass{article}
\usepackage{pstricks}
\usepackage{ifpdf}

\newpsstyle{bgCyan}{fillstyle=solid,fillcolor=cyan!10,linestyle=none,framesep=6pt}
\ifpdf
  \def\pBox#1{\raisebox{-.5\height}{\psframebox[style=bgCyan]{{%
    \tabular{@{}c@{}}#1\endtabular}}}}
\else
  \def\pBox#1{\psframebox[style=bgCyan]{{%
    \tabular{@{}c@{}}#1\endtabular}}}
\fi
...
