[wp-hackers] update $wp_query->post->guid fails

[Will Anderson]

Is there a reason why the URL is used? From a GUID definition standpoint,
the post's address meets the criteria (it should be globally unique [1]),
but from a user's standpoint, it has a lot of potential for confusion for
people who are (a) new to the WP DB and (b) don't already know what a GUID
is.

I guess what it boils down to is, why isn't something like the PHP uniqid()
function [2] used instead?
