Inconsistent printf placeholders

Hello.

A recent commit 6612185883 introduced two error messages that are
identical in text but differ in their placeholders.

- pg_fatal("could not read file \"%s\": read only %d of %d bytes",
- filename, (int) rb, (int) st.st_size);
+ pg_fatal("could not read file \"%s\": read only %zd of %lld bytes",
+ filename, rb, (long long int) st.st_size);
...
- pg_fatal("could not read file \"%s\": read only %d of %d bytes",
+ pg_fatal("could not read file \"%s\": read only %d of %u bytes",
rf->filename, rb, length);

I'd be happy if the two messages kept consistency. I suggest aligning
types instead of making the messages different, as attached.

regards.
