PostgreSQL RDBMS
A PostgreSQL RDBMS is a cross-platform object-relational database management system.
- Context:
- It can (typically) be a C Program.
- It can be access by a PostgreSQL Client, such as psql.
- It can process a PostgreSQL Statement.
- Example(s):
- PostgreSQL v14.1 (~2021-11). http://www.postgresql.org/ftp/source/v14.1/
- …
- PostgreSQL v9.5.4 (~2016-01). http://www.postgresql.org/ftp/source/v9.5.4/
- PostgreSQL v9.4.9 (~2016-12). http://www.postgresql.org/ftp/source/v9.4.9/
- PostgreSQL v9.2.18 (~2012-09). http://www.postgresql.org/ftp/source/v9.2.4/
- PostgreSQL v9.1.9. http://www.postgresql.org/ftp/source/v9.1.9/
- PostgreSQL v7.0.3 (2000-05).
- PostgreSQL v6.3.2 (1998-03).

- QUOTE: PostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video. It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, ODBC, among others, and exceptional documentation.
An enterprise class database, PostgreSQL boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, asynchronous replication, nested transactions (savepoints), online/hot backups, a sophisticated query planner/optimizer, and write ahead logging for fault tolerance. It supports international character sets, multibyte character encodings, Unicode, and it is locale-aware for sorting, case-sensitivity, and formatting. It is highly scalable both in the sheer quantity of data it can manage and in the number of concurrent users it can accommodate. There are active PostgreSQL systems in production environments that manage in excess of 4 terabytes of data. Some general PostgreSQL limits are included in the table below.

- PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X.[1] It is released under the PostgreSQL License, which is an MIT-style license, and is thus free and open source software. PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of volunteers employed and supervised by companies such as Red Hat and EnterpriseDB.[2] It implements the majority of the SQL:2008 standard,[3] is ACID-compliant, is fully transactional (including all DDL statements), has extensible data types, operators, index methods, functions, aggregates, procedural languages, and has a large number of extensions written by third parties.
The vast majority of Linux distributions have PostgreSQL available in supplied packages. Mac OS X, starting with Lion, has PostgreSQL server as its standard default database in the server edition,[4][5] and PostgreSQL client tools in the desktop edition.
