For binary compatability of the databases across architectures,

use pointers to arrays, not pointers to structs.  It is now possible
to create databases on sparc64 and use them on i386 and vice versa.
Kristaps@ can't think of anything else that might be required, either.
Put this in now such that we can move on.
