-        Checks the pages of the specified relation to see if they are valid

-        the given fork are to be verified.  <parameter>fork</parameter> can
-        be <literal>main</literal> for the main data
-        fork, <literal>fsm</literal> for the free space
-        map, <literal>vm</literal> for the visibility map,
-        or <literal>init</literal> for the initialization fork.  The
-        default of <literal>NULL</literal> means that all forks of the
-        relation should be checked.  The function returns a list of block
-        numbers that appear corrupted along with the path names of their
-        files.  Use of this function is restricted to superusers by
-        default, but access may be granted to others
-        using <command>GRANT</command>.
