Even more, then, I suspect the original server. If bad data made it
in such that you can't COPY it out, then it'll be bad everywhere you
go.

What you need to do is figure out what table it's on and what
record(s) it is. I think you might want to try playing with
pg_filedump to get some ideas. If all else fails, you can get the
data on either side of it by SORTing from the top of the table and
the bottom. You can then select all that into a file, and put it
into a freshly-created table. Not ideal, but it'll get you there.
Others will undoubtedly have more elegant solutions.

By the way, the potential for inserting bad records is one reason we
always specify ECC RAM for database machines.
