I've attached a patch to do this, and also add INT64_MODIFIER to
pg_config.h.in: 0001-modifier.diff

I reran autoconf, and just for convenience I've attached the resulting
changes to configure: 0002-configure.diff

Then there are the rm_identify changes: 0003-rmid.diff

Finally, the xlogdump patch using INT64_MODIFIER: 0004-xlogdump.diff

I can confirm that this series applies in-order to master, and that the
result builds cleanly (including after each patch) on my machine, and
that the resulting pg_xlogdump works as expected.

NOTE: I do not know what to do about pg_config.h.win32. If someone tells
me what to do, I can submit another patch.

Two of the extra calls to psprintf in pg_xlogdump happen at most
RM_MAX_ID*16 (i.e. O(record-types) not O(records)) times, and the other
two happen just before exit. It would be easy to use a static buffer and
snprintf, but I don't think it's worth doing in this case.
