Use \lineto or \moveto for lines (\closepath draws a strait line to the
beginning of the path):
\documentclass{article}
\usepackage{pst-plot}
\definecolor{SuperLightBlue}{cmyk}{0.2,0,0,0}
\begin{document}
\begin{pspicture}(4,4)
\psaxes{->}(4,3)
\pscustom[fillstyle=solid,fillcolor=SuperLightBlue,linecolor=blue]{%
\moveto(0,2)
\psplot[algebraic]{2}{0}{0.25*x^2+1}% x=2...0
\closepath
}
\end{pspicture}
\begin{pspicture}(4,4)
\psaxes{->}(4,3)
\pscustom[fillstyle=solid,fillcolor=SuperLightBlue,linecolor=blue]{%
\psplot[algebraic]{0}{2}{0.25*x^2+1}% x=0...2
\lineto(0,2)
\closepath
}
\end{pspicture}
\end{document}
