Number of heap blocks scanned. Because the
<link linkend="storage-vm">visibility map</> is used to optimize scans,
some blocks will be skipped without inspection; skipped blocks are

equal to <structfield>heap_blks_total</> when the vacuum is complete.
This counter only advances when the phase is <literal>scanning heap</>.
