I am not sure, but a couple of things which would make it possible are.
1) PostgreSQL does generally report which file was corrupted.
2) The PostgreSQL log output rarely looks similar to regular data, so it should be obvious to anyone looking what is wrong if they do look at the contents of the file.
And most importantly they can always contact a PostgreSQL expert who could repair it.
