Logical backups play a significant role for Disaster and Recovery Planning (DRP).Logical backups are backups taken, for example using pg_dump or pg_dumpall, which generate SQL statements to obtain all table data that is written to a binary file. These are rules that we can set on each column that the database will enforce. To emulate a production system, we have restored two sample databases in our PostgreSQL server.
