We will move the old data files out of the way, run initdb, reload a
pg_dump with schema-only, then move the data files back into the proper
locations, and perhaps drop/recreate all indexes. They will have all
the features. They have just kept their raw data files.
How long does re-indexing the tables take vs. reloading and re-indexing?
