UUID type question
I'm *sure* I've seen this discussed on here before - infact I'm worried it might even have been me who asked the question !
But I've searched the archives without luck, so here goes :
Is there anything inherently "special" about the UUID type ? i.e. if I store a UUID in a text is it "worse" ? (I'm speaking here about performance & storage, obviously, not the fact that uuid enforces the formatting).
Thanks !

uuid is stored as 16 binary bytes.
Store it as text, and that's 36 chars (assuming UTF-8, double-that in
UTF-16, if that's possible in PG).
Or encode it as base-62 instead of hexa (base-16, with dashes), to use
only 22 chars as text (in UTF-8 or ASCII)

I love KSUID. I use it in all new projects. ;-)
