--clean drops the tables, not the data.

Well, you could just not use --clean, which would insert the data into
existing tables. But if you have conflicting data in your tables, you
need a more elaborate scheme, depending on how exactly you plan to
resolve those conflicts.
I think you might be a bit confused about the proper workflow with
pg_dump and pg_restore and therefore are not giving us accurate
information. Perhaps some more detail would help.
