I don't know if its the method you remeber or not but a program's stdio
can be address as files (on linux anyway) as /proc/self/fd/{0,1,2}. So
you could something like...
ps2pdf -r300 -g3300x5100 /proc/self/fd/0 /proc/self/fd/1
... which is kind of a round about way of telling ps2pdf to read from
stdin and write to stdout.
