This ignores the fact that relid and relpages are unsigned. I would
suggest adopting the same convention for OID as is used in pg_dump and
other places:
#define atooid(x) ((Oid) strtoul((x), NULL, 10))
You could actually use this same macro for reading relpages, but that's
probably abusing the notation. I'd use strtoul directly for relpages,
I think.

This (and other declarations) should be "Oid oid".
