Fix some duplicated values in tables The licenses table, along with the package_metadata table had duplicate values. This could happen as the unique constraints on those tables didn't properly account for the nullable fields. The duplicates in those tables also affected the license_sets, packages, package_derivations tables in a similar way. Finally, the guix_revision_package_derivations table was also affected. This commit adds a migration to fix the data, as well as the constraints. THe code to populate the licenses and package_metadata tables is also updated. 2019-08-04 09:39:40 +01:00			`-- Revert guix-data-service:fix_duplicated_licenses from pg`
