nope, that's a new one on me.  there are known problems with joins
of large tables (now fixed) and index retrievals (now fixed) but not
with scans without qualifications.

if you can reproduce this, please send much, much more information
(hardware, OS, exact schema and queries and some/all of the data) to 
bug-postgres@postgres.  thanks.
