no, but there is a general rule: if drivers are specified by optional
arguments, like [pdftex] in this case, then you can expect problems
when running your document in another mode. PSTricks needs dvips mode.
(auto-pdf does this internally in a separate run)
However, in nearly all cases, todays packages can detect the needed
driver itself, so there is no need to specify a driver.
Or alternative use the ifpdf construct:

\usepackage{ifpdf}% in this case already done by pst-pdf
\ifpdf
  \usepackage[pdftex]{web}
\else
  \usepackage[...]{web}
\fi
