Do we have nominations for a name?  The first idea that comes to mind
is "synchronized_scanning" (defaulting to ON).

Also, does anyone object to making pg_dump just disable it
unconditionally?  Greg's original gripe only mentioned the case of
clustered tables, but it'd be kind of a pain to make pg_dump turn it
on and off again for different tables.  And I could see people
complaining about pg_dump failing to preserve row order even in
unclustered tables.
