Get_post_types double calls....

[selnomeria]

get_post_types() has argument _builtin, not correctly implemented...

when i created custom QUERY, I have to call that function twice:

$args['post_type'] = array_merge(get_post_types(array('_builtin'=>true)),get_post_types(array('_builtin'=>false)));

so, its good, if there was a value of '_builtin'=>"ALL" , so it gets both of them, not only TRUE or FALSE ones...

It will save DATABASE calls!!

get_post_types() (without a parameter) should return all post types, regardless of the _builtin value.

It also does not perform any database calls, since post types are registered at runtime.

IMHO the docs are clear on this.
