Uh, deletion has nothing to do with writability of the file, and
everything to do with writability of the directory it's in. So you
could solve the stated problem without touching the Postgres code.
However, the answer to your question is that the mode is hardwired to
644 (rw-r--r--) by the umask call in src/backend/commands/copy.c.
