+1. Another thing I noticed is that we now have a fair amount of code
like this example in xlog.c:
errno = 0;
r = read(srcfd, buffer, nread);
if (r != nread)
if (r < 0)
errmsg("could not read file \"%s\": %m",
(errmsg("could not read file \"%s\": read %d of %zu",
path, r, (Size) nread)));
The short-read ereport has no errcode() call, meaning it will report
XX000, which seems like it's against project policy for foreseeable
errors. In this example ERRCODE_DATA_CORRUPTED seems better.
BTW, isn't the initial "errno = 0" dead code now?
