I suppose you tried M-x TeX-auto-generate-global on that day. I at last
understood the origin. In
/usr/local/texlive/2020/texmf-dist/tex/latex/standalone/standalone.cls
, there are lines
----------------------------------------------------------------------
\ifsa@pstricks
    \RequirePackage{pstricks}
\fi
----------------------------------------------------------------------
and this portion makes the generated ~/.emacs.d/auctex/standalone.el
enable pstricks support.

Maybe AUCTeX document should warn that TeX-auto-generate-global can
bring on unexpected side effects.

If "the same behaviour" means that TeX-PDF-from-DVI is set to "Dvips",
this is intentional. Please see the thread beginning with
