Furthermore, the “physical backup” does not have to be an immediate snapshot of the database state: if it was created in the past, replaying the WAL log from that point in time will resolve any internal inconsistencies.
Flexible
PostgreSQL is open source, so the code can be freely modified on all platforms: it can be adapted to work on any platform, including Windows, Solaris, OS X, and Linux. In addition, it can accommodate multiple users at the same time, blocking only concurrent updates to the same row.
Extensibility
Extensibility is a software engineering principle that speaks to future growth. PostgreSQL offers great extensibility because it operates on a catalog basis, meaning information is stored in databases, columns, tables, etc. Just-in-time (JIT) compilation of expressions allows you to write your code from different programming languages without having to recompile your database and define your data types. This ability to modify any operation spontaneously makes it especially suitable for implementing india whatsapp number data new storage structures and applications quickly.
Replication
PostgreSQL includes built-in synchronous replication that guarantees that for each write, the primary node will wait until a mirror node has written the data to its transaction log. Transaction durability can be specified per database, session, and user, regardless of their synchronization. This helps speed up the transaction as there is no need to confirm that the transaction reaches a synchronous node, especially when some flows do not require these guarantees.
Use cases
PostgreSQL is practically everywhere: it is among the top five most used databases today, behind only MySQL. Major companies such as Bloomberg, Goldman Sachs and Nokia have PostgreSQL running in their backend.
PostgreSQL can be used by a variety of industries and is not limited to just one. Here are a couple of examples where PostgreSQL can be used today.
