Good point. Now that we are getting rid of some of the other options,
we don't need to worry about consistency with them, and I think we
should just use "--statistics".

I noticed that --statistics (i.e., the current --with-statistics) causes
statistics to be dumped even when used with --data-only or --schema-only.
So, as far as I understand, here are the possible combinations of dump
targets and options:
schema, data, stats: --statistics
schema, data: (default)
schema, stats: --schema-only --statistics
data, stats: --data-only --statistics
schema only: --schema-only
data only: --data-only
stats only: --statistics-only
This makes me wonder if --no-data and --no-schema are still necessary.
They were also introduced in v18, but might now be redundant. If so,
should we consider removing them?
If we do keep them, we could also use --no-schema --statistics to
dump data and statistics, but I find --data-only --statistics more intuitive.
