savepoint name vs prepared transaction name

[Grzegorz Jaśkiewicz <gryzman@xxxxxxxxx>]

Is there any reason, why I can't put quotes around name of savepoint, but I have/can do this for prepare transaction ? 

Ie: 
SAVEPOINT 'foo'; --- doesn't work
SAVEPOINT foo; --- all grand

PREPARE TRANSACTION 'foo'; --- grand
PREPARE TRANSACTION foo; refuses to work. 

It is quite confusing, I feel like some consistency would be nice here.
