DeepGuard breaks PostgreSQL database startup
Basically the database fails to start with a error 487.
The DeepGuard forces ASLR which messes with the Inter-process communications of the database (it does massive usage of shared memory).
F-Secure shall blacklist/disable the DeepGuard activities for postgres.exe processes BY DEFAULT, please do that, otherwise it just wastes other people's time in tech support.
DeepGuard just breaks PostgreSQL, and on top of that... randomly !
