pg_dump: Fix query for gathering attribute stats on older versions. Commit 9c02e3a986 taught pg_dump to retrieve attribute statistics for 64 relations at a time. pg_dump supports dumping from v9.2 and newer versions, but our query for retrieving statistics for multiple relations uses WITH ORDINALITY and multi-argument UNNEST(), both of which were introduced in v9.4. To fix, we resort to gathering statistics for a single relation at a time on versions older than v9.4.
