Improve server code to read files as part of a base backup.
Don't use fread(), since that doesn't necessarily set errno. We could
use read() instead, but it's even better to use pg_pread(), which
allows us to avoid some extra calls to seek to the desired location in
the file.
Also, advertise a wait event while reading from a file, as we do for
most other places where we're reading data from files.
Patch by me, reviewed by Hamid Akhtar.
