Try making the dump from the 7.4 server using 8.1's pg_dump(all).

If you've already wiped the 7.4 installation then you'll have to deal
with the incompatibilities yourself.  It looked like setting
default_with_oids to true in the 8.1 server would help (although do you
*really* need to preserve OIDs in your dump?  That -o switch is pretty
well deprecated these days).  The "cannot delete from a view" is
probably coming from an attempt to "DELETE FROM pg_shadow", which you
can ignore.  You didn't show us any other problems.
