By default, pg_dump/pg_restore uses a COPY command for each table, and
each COPY executes as a single transaction, so you shouldn't see the row
count growing like that. Is the dump file in --inserts format?

pg_restore -s foo
pg_restore -a -1 foo

doesn't seem too complicated to me. Am I missing something?
