Subject: Commit failing test for unique constraints: When a table has two or more unique
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=365d06b716eb2b3894d83291c612b116ade1e9d7;p=dbsrgits%2FDBIx-Class-Historic.git

Commit failing test for unique constraints: When a table has two or more unique
constraints, and you satisfy one, you get a partial key in the WHERE clause.

This required adding two unique constraints to the 'track' table, and fixing up
a couple of cases where we had duplicate values.
