Well, the file clearly isn't accessible by the postgres user (or
whatever user you're using in Windows). The file is opened from a
PostgreSQL backend process, not using your regular user.

It clearly states that "format" accepts the same values as COPY and even
provides a link to COPY documentation. Placing this kind of details onto
both pages would be just maintenance burden.

What else could PostgreSQL tell you? It tried to open the file, did a
regular open() or something like that and it failed with EACCES error
code. That's all the info there is.
