Both InnoDB and PostgreSQL - as well as many other databases - use a technique called multi-version concurrency control (MVCC) to provide transaction isolation: transactions should not see the work of other, uncommitted transactions. MVCC means that, when a row is updated, the database stores both the old and new versions of the row.
If you are one who is using PostgreSql as your Back-end Database Server for your work, then obviously you need a backup solution, so here this is my try for a small solution for Automated Backup Job in Bash Shell Script.
