We have faced different levels of corruption related to databases in PostgreSQL. We need to identify whether it was deleted manually by mistake or was due to hardware failure. In case of hardware failure, first, we need to fix the hardware issue or migrate our database to new hardware and then perform a restore, as mentioned below.

Why not just create another database on the same instance? We split databases by function/team to give each team full autonomy over their schema, And if someone screws up, it breaks their cluster, not all databases. So you put multiple MySQL servers on a single machine instead of multiple databases inside one MySQL instance.
