Any thoughts on using/improving these structures?

Hearing no objections, here is the latest patchset.

0001 - Changes input/output functions of pg_ndistinct to the format described earlier.
0002 - Changes input/output functions of pg_dependencies to the format described earlier.
0003 - Makes some previously internal/static attribute stats functions visible to extended_stats.c, because the exprs attribute is basically an array of partially filled-out pg_statistic rows.
0004 - Adds pg_restore_attribute_stats(), pg_clear_attribute_stats(), in the pattern of their relation/attribute brethren.
0005 - adds the dumping and restoring of extended statistics back to v10. No command line flag changes needed.
 

Rebased. Enjoy.
