As long as the message includes the file name, which it surely oughta,
I don't see that we need any explanation of what Postgres thinks the
file is for. If someone cares about that they can reverse-engineer
it from the file name; while as you said upthread, most of the time
the directory path is going to be the key piece of useful information.
So +1 for "could not write file".

I think Andres' argument is a thinly veiled version of "let's put the
routine name into the message text", which there definitely is project
policy against (see 49.3.13 in the message style guide). If you want to
know the code location where the error was thrown, the answer is to get
a verbose log, not to put identifying information into the user-facing
message text. And this is only partially-identifying information,
which seems like the worst of both worlds: you've got confused users and
overworked translators, and you still don't know exactly where it was
thrown from.
