Thread: DISABLE_PAGE_SKIPPING option for vacuumdb
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.

Okay, I thought it would be useful for user who want to vacuum with disable_page_skipping specified table but it's non-essential. I pull it back. Thanks.
