More than 1 place?

pg_dump is dumping your functions and for each function it looks up
the argument type by the oid of the type.  For one function there
is a type whose oid is 779927, but there is no row in pg_type with
that oid.

I don't think that get_disid(text,text) is necessarily the
culprit, because the routine aborts pg_dump as soon as it hits that
error (src/bin/pg_dump/common.c:findTypeByOid()), whereas you seem
to be getting a lot of text after the error.  I suspect that
stderr is getting sent and then the stdout buffer is flushed as
the program exits.

Look in pg_proc for a function that tries to use a type of 779927:

 select proname, proargtypes, prorettype from pg_proc;

That will be the one that is causing the problem.  (Of course the
next question is how it got that way.)
