I see what you're saying.  I thought it had worked, but when I looked at
the dump file there was no data.  Thanks.

The temp table is only visible inside the context of the transaction
under which it was created.

A pg_dump session will create an independent transaction context, where
the table won't be visible, alas.

So you can't use pg_dump to dump the data out.

You may, however, use COPY to dump it out yourself.

  select * into temp table foo from bar;
  copy foo to '/tmp/foo_contents.txt';
