Obsolete db path in mentat-cleanup.py.conf
There is still path to PostgreSQL 12 in cleanup config file. It should not make hard problems, because it is probably there only to have a possibility to find out database size. It could be shortened to not include version, or this functionality removed altogether.
(There is also longer threshold than on our production, which I recommend to leave as is now, as it could cause for users using default config to lose 3 months of data.)
