~5,000 locations have multiple `cvs:` concordances

[Simon Willison]

This SQL query shows locations with multiple cvs: concordances:

select location.public_id, count(*), array_agg(authority || ':' || identifier)
from concordance_location join concordance_identifier on concordance_identifier.id = concordanceidentifier_id
join location on location_id = location.id
where authority = 'cvs' group by location.public_id
having count(*) > 1
order by count(*) desc

There are a LOT - grouping by their duplicate count gives:

count	n
2	4193
3	358
4	259
5	189
6	64
7	9
8	2
