I think PostScript support is often disabled by default because of
security issues: PostScript is a very versatile language and Ghostscript
has had a series of problems due to its inability to “sandbox”
PostScript code.
A particularly important issue is thumbnail generation: you could find
yourself running PostScript code without explicitly opening a file.
FWIW, I resort to gv (or ps2pdf) when I need to open a PostScript that I
deem trustworthy.
Leo, Mark, WDYT?
Thanks,
Ludo’.
