There are some functions in contrib/fuzzystrmatch that seem like they'd
help you find candidate duplicates. contrib/pg_trgm and text search
might also offer promising tools.
What's really a duplicate sounds like a judgment call here, so you
probably shouldn't even think of automating it completely.
