you might try dumping the schema and data separately:

pg_dump -a yourdb >yourdb.data
pg_dump -s yourdb >yourdb.schema

then edit the schema without touching the data, then

psql newdb <yourdb.schema
psql newdb <yourdb.data


For speed, you may want to split the schema where the indeces are
created, and run that after the data load.

psql newdb <yourdb.schema.tables
psql newdb <yourdb.data
psql newdb <yourdb.schema.indices
