In this case we must have <literal>db_table:select</> in addition to
! <literal>db_table:update</>, because <literal>t1.a</> is referenced
within the <literal>WHERE</> clause. Column-level permissions will also be
checked for each referenced column.

--- 358,364 ----
</synopsis>

In this case we must have <literal>db_table:select</> in addition to
! <literal>db_table:update</>, because <literal>t1.z</> is referenced
within the <literal>WHERE</> clause. Column-level permissions will also be
checked for each referenced column.
</para>

(It is unclear to me why the same example is cited twice here, but the
text around them is consistent with that.)
