This needs to be re-prepared as a branch from lp:launchpad/db-devel, and proposed as a merge into lp:launchpad/db-devel. We can't land database patches against devel directly, except in a few specialised circumstances. Furthermore, the code branch (lp:~abrody/launchpad/https-mirror) may not declare the DB branch as a prerequisite; it must instead be a separate branch that doesn't itself contain the DB changes. This is all because database and code updates are deployed from separate branches; see https://dev.launchpad.net/PolicyAndProcess/DatabaseSchemaChangesProcess.
