This works:
pdftoppm -f 5 -singlefile -gray demo.pdf >demo.pgm
This fails to parse the PDF properly:
cat demo.pdf | pdftoppm -f 5 -singlefile -gray - >demo.pgm
This has the same effect:
pdftoppm -f 5 -singlefile -gray - <demo.pdf >demo.pgm
These warnings are output:

This used to work with poppler 0.41.0. I have tried a couple of versions since
then, all of which suffer from the same problem. 0.47.0 is still broken.
I believe the other utils have similar problems with reading from stdin.</pre>
