Colin Watson has proposed merging lp:~cjwatson/launchpad/package-cache-indexes into lp:launchpad.

Commit message:
Add (xPN, archive) indexes on package cache tables.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)

For more details, see:
https://code.launchpad.net/~cjwatson/launchpad/package-cache-indexes/+merge/296379

Add (xPN, archive) indexes on package cache tables.  This makes the upcoming changes to {Source,Binary}PackageNameVocabulary to use the package caches perform much better - a few milliseconds vs. about a second on dogfood for reasonably typical queries.

Your team Launchpad code reviewers is requested to review the proposed merge of lp:~cjwatson/launchpad/package-cache-indexes into lp:launchpad.
