My goodness, that's a pretty obsolete system :-(. You do realize that
7.3.x was up to 7.3.21 by the time it was obsoleted?
My recollection is that this has been seen to happen when there were for
some reason duplicate rows in pg_shadow --- pg_dump does something like
"SELECT FROM pg_class JOIN pg_shadow ON relowner = usesysid", so it
would get multiple copies of any table that joined to multiple pg_shadow
entries. How you got into that state is harder to say, but if you can
get rid of the duplicate entries then your dump would go back to a sane
state.
