Merge lp:~cjwatson/launchpad/db-packageset-score-rename into lp:launchpad/db-devel

[Colin Watson]

Rename Packageset.score column to Packageset.relative_build_score.

== Summary ==

Continuing the saga of bug 1000570, which reports a badly-named column on Packageset. This deals with actually throwing the Ring into Mount Doom, but there's still some cleanup to do in the Shire afterwards.

== Proposed fix ==

lp:~cjwatson/launchpad/packageset-score-rename-support (which has landed on stable but has yet to be deployed; I'll make sure not to land this until that's happened) arranges for the appserver code to tolerate the column being called either score or relative_build_score. This patch actually renames the column.

== LOC Rationale ==

+8, but it will drop to zero if and when this is eventually collapsed into a new base version of the schema.

== Tests ==

bin/test -vvct TestBuildPackageJobScore -t TestBuildQueueManual

[Stuart Bishop (stub)]

Looks fine.
