Right. During the constructor of the Zend_Db_Table class, it queries the
metadata for the table from the database, so Zend_Db_Table is able to
discover the primary key column(s) in most cases.

Typically, the only need to declare $_primary is if the DBMS doesn't report
its primary key column(s), or if you defined your table with no primary key
constraint (which isn't recommended anyway).
