These are pg_dump(all) executable from postgresql-8.1.4
I copied them onto my postgresql-7.4.2 server and chmod to executable.

User postgres have full permission under /db/pg_backup, so I don't know
how you could use 8.1's pg_dump(all) on 7.4 server.

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.
