Parallel partial replica workflow
1. Set up DDL if needed e.g. using the pg_restore --section=pre-data machinery.
2. Open a pool of connections to the destination server.
3. Save out a snapshot on the source server as usual in pg_dump -j.
4. Open j connections to the source server.
5. For each source connection, dump table data as specified (possibly via COPY BINARY) directly to
an open target connection, or buffer if no open target connections are available.
