There are not many reasons to treat .ps differently than .pdf
nowadays.  So I think the question is whether to add them both to
completion-ignored-extensions or to remove them both from it.

I want to remind that completion-ignored-extensions is used also by
dired to display files with these extensions in a different face.
There is actually no problem to have .ps and .pdf files name displayed
differently than other files, but what is bad is that dired-x uses
completion-ignored-extensions to omit files from dired buffers.
.ps, .pdf and .dvi files contain the resulting material that users
very likely may want to view via external programs calling a shell
command on them.  So removing them from the dired buffer is not
a good choice.  Omitting the files in dired-x is controlled by the
variable dired-omit-extensions created from the value of
completion-ignored-extensions.  I suggest to remove .pdf and .dvi
from the default value dired-omit-extensions.
