![]() ![]() Go through the following steps in order to install PostgreSQL server. PostgreSQL 13.1, Windows 10 64 bit Install PostgreSQL You do not need to check in the registry for any uninstalled or unremoved files, in the system, that might exist if you install exe or msi version of PostgreSQL server. You can just delete the folders and you can again setup the new version of PostgreSQL anytime. You do not need to worry about updating the PostgreSQL. You do not need to worry about anything goes wrong during uninstall your PostgreSQL server. The advantage of installing zip version of the PostgreSQL is that your registry does not get modified and you do not need to restart your system (if required). I am also going to show you some basic commands for listing all database, switching to another database, creating a new database, showing all tables, creating a new table, database backup, database import. I will show you how to setup username and password for your PostgreSQL database server. * hstore improvements, including new functions and greater data capacity.In this example I will show you installing PostgreSQL zip archive in Windows environment. The output is now available in JSON, XML, or YAML format, and includes buffer utilization and other data not previously available. This helps optimize some automatically-generated queries, such as those produced by object-relational mappers (ORMs). * Multiple performance enhancements for specific types of queries, including elimination of unnecessary joins. * New contrib module pg_upgrade to support in-place upgrades from 8.3 or 8.4 to 9.0. It is substantially faster in most cases, and no longer results in index bloat. This command now rewrites the entire table and indexes, rather than moving individual rows to compact space. Also, a "payload" string can be sent with each event, rather than transmitting just an event name as before. Pending events are now stored in a memory-based queue rather than a table. * New high-performance implementation of the LISTEN/NOTIFY feature. * New and enhanced security features, including RADIUS authentication, LDAP authentication improvements, and a new contrib module passwordcheck for testing password strength. ![]() These provide a generalized version of unique constraints, allowing enforcement of complex conditions. 15.3 Older versions Advertisement PostgreSQL is a relational database system that belongs in the class of open-source software that stands out for its robustness, scalability, and accomplishment of SQL standards. Mass updates to unique keys are now possible without trickery * New trigger features, including SQL-standard-compliant per-column triggers and conditional trigger execution. * More advanced reporting queries, including additional windowing options (PRECEDING and FOLLOWING) and the ability to control the order in which values are fed to aggregate functions. PL/pgSQL is now installed by default, and PL/Perl and PL/Python have been enhanced in several ways, including support for Python3. Functions can now be called using named parameters. The DO statement supports ad-hoc or "anonymous" code blocks. * Broadly enhanced stored procedure support. Large objects (BLOBs) now support permissions management as well. GRANT/REVOKE IN SCHEMA supports mass permissions changes on existing objects, while ALTER DEFAULT PRIVILEGES allows control of privileges for objects created in the future. * Easier database object permissions management. The net effect is to support a single master with multiple read-only slave servers. This advance consists of two features: Streaming Replication, allowing continuous archive (WAL) files to be streamed over a network connection to a standby server, and Hot Standby, allowing continuous archive standby servers to execute read-only queries. * Built-in replication based on log shipping. To install PostgreSQL on your computer please download one of the following files (Note that downloading any of them means your agreement with PostgreSQL License ): PostgreSQL 15.2: 64bit, PostgreSQL 14.7: 64bit, PostgreSQL 13.10: 64bit, PostgreSQL 12.14: 64bit, 32bit, PostgreSQL 11.19: 64bit, 32bit, PostgreSQL 10.23: 64bit, 32bit. ![]()
