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?
