Now there's another problem, this time with acs-mail:
There are 4 referential integrity indexes duplicated between upgrade-4.6-4.6.1 and upgrade-4.6.1-4.6.2. I'm not sure where they really belong, so I removed them from the latter.
If this was wrong (which the Oracle version seems to indicate, but I forgot to check that before I committed my fix), then please change back.
