Hi,

Attached patch add --disable-page-skipping option to vacuumed command for 9.6.
If by any chance the freeze map causes the serious data corruption bug
then the user will want to run pg_check_visible() and vacuum with
DISABLE_PAGE_SKIPPING option to the multiple tables having problem.
In this case, I think that this option for vacuumdb would be convenient.

Please give me feedback.

Regards,
