Performs a little-endian comparison of byte strings.
If the existing value in the database is not present or shorter than
`param`, it is first extended to the length of `param` with zero
bytes.
If `param` is shorter than the existing value in the database, the
existing value is truncated to match the length of `param`.
The smaller of the two values is then stored in the database.
