Hello.. My name is Rian.

I have a problem, my Database attacked by ransomware virus. Some file
has encrypt. for pg_hba and postgresql.conf i have a backup, but for
some file like pg_filenode.map i dont have.

this a log when i start the postgres:

2017-05-08 10:08:17 ICT FATAL:  relation mapping file
"global/pg_filenode.map" contains invalid data

Looks like the PGDATA directory was encrypted. Unless you have a backed
up dump file that you created using pg_dump or have been archiving WAL
files you are not going to be able to reclaim the database without
getting the files unencrypted.


thanks for kindness.
