In Gerrit1 a number of folks signed up as "them@gmail.com" but then later signed up as "them@android.com". This SQL script loads up a temporary table with a mapping of "them@gmail.com -> them@android.com" and applies it across all user data. The conversion allows the user to login under either email address from the Google Account OpenID provider, and retains as much of their prior details as possible. Signed-off-by: Shawn O.
