Well, you could try copying the physical file for pg_amop from template1
to mydb (and then reindexing it again).  I am not holding out a lot of
hope though.  I think you're most likely going to run into a dead end,
unfixable problem before you get any data out.

Maybe you should forget about pg_dump and just see if you can COPY
the tables you care about.
