[fw-general] Why does Zend_Db_Table's method info('primary') starts with 1?

[Thomas D.]

Hi,

Zend_Db_Table's method info('primary') will return an array containing all
the primary keys.
I would expect, that the first key should have the offset 0, but the
returned array starts with offset 1.

Is there any reason why the array starts with index 1?
