Instead of having a configure-time DEFAULT_ATTSTATTARGET, store -1 in
attstattarget to indicate 'use the default'. The default is now a GUC variable default_statistics_target, and so may be changed on the fly. Along the way we gain the ability to have pg_dump dump the per-column statistics target when it's not the default. Patch by Neil Conway, with some kibitzing from Tom Lane.
