I'm missing nothing :)
"uniqueidentifier" (128-bit unique value) data type fot PostgresSQL
exists and is used at least by me. It utilizes functionality of uuid
library from widely used in Linux e2fsprogs package. Uuid library itself
can generate UUIDs with MAC/time but if /dev/urandom was detected the
true random 16 bytes will be used by default.
And yes, this type is great for primary keys.
