PostgreSQL (http://www.PostgreSQL.org/) has many useful features. It provides enterprise-level services, including performance, unique features, and scalability. It has a very supportive community and very good documentation.

PostgreSQL was started as a project at the University of California at Berkeley (UCB), then it was developed by the community in 1996.

So far, PostgreSQL is actively developed by the PostgreSQL community as well as universities. The following time frames show the history of PostgreSQL's development:

• 1977-1985, the Ingres project: Michael Stonebraker created a relational database management system (RDBMS) based on the formal relational model.
• 1986-1994...

PostgreSQL provides enterprise-level services that guarantee the continuation of the business. For example, PostgreSQL supports replication, which enables the developers to provide HA solutions. PostgreSQL can integrate data from different data sources; this makes it easy for developers to use it for ETL jobs. In addition, PostgreSQL security is treated as a first-class citizen. Security update patches are shipped in minor releases to make it easier for administrators to upgrade PostgreSQL.

Finally, the features of PostgreSQL are endless: PostgreSQL provides advanced SQL statements, very rich extensions, and interactive tools.

Replication allows data from one database server to be replicated...

PostgreSQL can be installed on almost all modern operating systems. It can be installed on all recent Linux distributions, Windows 2000 SP4 and later, FreeBSD, OpenBSD, macOS, AIX, and Solaris. Also, PostgreSQL can work on various CPU architectures, including x86, x86_64, and IA64. You can check whether a platform (operating system and CPU architecture combination) is supported by exploring the PostgreSQL build farm at http://buildfarm.postgresql.org/. You can compile and install

In order to automate PostgreSQL installation and to reduce server administrative tasks, it's recommended you use PostgreSQL binaries, which come with the operating system packaging system. This approach normally has one drawback: binaries that aren't up to date. However, PostgreSQL's official website maintains the binaries for the most common platforms, including BSD...

PostgreSQL is an open source, object-oriented relational database system. It supports many advanced features and complies with the ANSI-SQL standard. It has won industry recognition and user appreciation. The PostgreSQL slogan, The world's most advanced open source database, reflects the sophistication of PostgreSQL's features. It's a result of many years of research and collaboration between academia and industry. Start-up companies often favor PostgreSQL due to licensing costs, and it can aid profitable business models. PostgreSQL is also favored by many developers because of its capabilities and advantages.

PostgreSQL can be used for OLTP and OLAP applications. It is ACID-compliant; thus, it can be used out of the box for OLTP applications. For OLAP applications, PostgreSQL supports the Windows functions, FDW, table inheritance, declarative table partitioning...

1. What's the difference between logical and streaming replication?
2. Why do PostgreSQL security updates often require minimal downtime?
3. What's the name of the main process of the PostgreSQL server?
4. When installing PostgreSQL on Linux, you don't need to provide a password; what's the reason for this?
5. What is Greenplum?
6. What's meant by a physical backup and what utilities does PostgreSQL provide to achieve this?
7. A developer destroyed some data by mistake on a database cluster. Do you think the administrator can recover PostgreSQL to a specific point in time?
8. We briefly mentioned the CLUSTER and REINDEX statements. Use the psql tool's client meta-command to get the syntax for the CLUSTER and INDEX statements.
9. Why is the psql tool very handy in shell scripting?
