That's a bit odd. There are scenarios where all-zero pages can
legitimately appear in a PG file --- specifically, if PG extends
the table and the OS completes that task, but then there's a crash
before PG gets to write any data into the new page. Conceivably a
crash during a bulk data load process could result in half a dozen
such pages together, but it seems improbable. Try looking at the
data on the preceding and following pages --- does it look like there's
something missing?
