PostgreSQL should survive a crash just fine; it seems like your databases are running with unsafe storage (that doesn't honor fsync). If the backup from 2 months ago is a physical backup and you have WAL archives, you can simply recover up to now. If it is just a pg_dump, then you can either live with 2 months of data loss or you hire professionaly that might be able to get some of your data back. If you go for the second option, take a copy of the broken database before doing anything else with it. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
