Patch attached.

  * removes --with-data and --with-schema (redundant)
  * renames --with-statistics to just --statistics

I kept --statistics and --no-statistics for both pg_dump and
pg_restore, because: (a) I think it's good to have consistent options
between those two programs; and (b) it allows us to potentially change
the default to include statistics in the future. That leaves some
redundancy of the options, which some have expressed annoyance over,
but it doesn't seem like a major point of objection.
