For now, remove these lines from xlogdump.c, l.82-86
if (((XLogPageHeader) pageBuffer)->xlp_magic != XLOG_PAGE_MAGIC)
{
printf("Bogus page magic number %04X at offset %X\n",
((XLogPageHeader) pageBuffer)->xlp_magic, logPageOff);
}

The program is unfortunately release specific, which is not very useful
for you now. D05E is the correct magic number for 8.2.4.

I'll update that program once we have the main software done for 8.3. I
was hoping that Diogo would continue to support it.
