Transfer statistics during pg_upgrade. Add support to pg_dump for dumping stats, and use that during pg_upgrade so that statistics are transferred during upgrade. In most cases this removes the need for a costly re-analyze after upgrade.
Some statistics are not transferred, such as extended statistics or statistics with a custom stakind. Now pg_dump accepts the options --schema-only, --no-schema, --data-only, --no-data, --statistics-only, and --no-statistics; which allow all combinations of schema, data, and/or stats. The options are named this way to preserve compatibility with the previous --schema-only and --data-only options. Statistics are in SECTION_DATA, unless the object itself is in SECTION_POST_DATA. The stats are represented as calls to pg_restore_relation_stats() and pg_restore_attribute_stats().
