                filesize = BufFileSize(file);
                if (filesize < 0)
                        ereport(ERROR,
                                        (errcode_for_file_access(),

Commits

  1. Have BufFileSize() ereport() on FileSize() failure.

  2. Use 64 bit type for BufFileSize().

  3. Adjust trace_sort log messages.

  4. Fix some sloppiness in the new BufFileSize() and BufFileAppend() functions.
