pstricks randomgray text and error messages

On various macs running various installations of texlive, I get one extra line of text in output, something like this:

“tx@Dict begin Rand end{<}randomgraygray tx@Dict begin Rand end{<}gray tx@Dict begin Rand end{<}randomgray” without the braces { }

MWE

documentclass[10pt]{article} 
usepackage{pstricks}
begin{document}
section{Start}
Here we go.
end{document}

I am using Mojave with Texshop and a fresh install of texlive 2019, but I have had this problem on various computers over the years. Doesn’t matter if I use xelatex or plain latex

The log file contains messages like this:

/usr/local/texlive/2019/texmf-dist/tex/generic/pstricks/pstricks.tex:662: Illeg
