What this means is a read past EOF --- that is, read() returned fewer
bytes than requested (perhaps none at all) but did not signal an error.
A potential ultimate cause is corrupt indexes that contain pointers
leading past the end of the table. Which sounds a whole lot like the
VACUUM bug fixed in 8.0.14 and other recent releases.
