Checks the pages of the specified relation to see if they are valid
enough to safely be loaded into the server's shared buffers. If
given, <parameter>fork</parameter> specifies that only the pages of
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>.
