Subject: [PATCH] Handle hypothetical object size greater than 2^32B.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hypopg_relation_size wasn't careful when converting the number of blocks to
bytes, as the result can overflow an int32.

Per report from Jan Koßmann.
