I don't think that's a very good solution; the reason the magic number
changed is that some of the record formats changed.  Jason needs a copy
that's actually appropriate to 8.2.

Howver there is something odd here, because the value of XLOG_PAGE_MAGIC
comes from src/include/access/xlog_internal.h and not from the text of
xlogdump.c itself.  What it looks like to me is that Jason compiled it
against the wrong set of Postgres header files.
