How to PostgreSQL- Getting started
In this guide, You will learn PostgreSQL through many practical examples. PostgreSQL is a fully featured object-relational database with many enterprise features.
PostgreSQL is a general purpose and object-relational database management system, the most advanced open source database system.
It is also highly extensible and allows users to define internal functions in C, C++, Java, Perl, TCL, Python, Ruby, PHP and PL/PgSQL.
PostgreSQL is developed by the PostgreSQL Global Development Group, a diverse group of many companies and individual contributors. PostgreSQL is free and open source software. Its source code is available under PostgreSQL license.
- Easy to install and configure
- The Web Control Panel
- Adminer administration frontend for PostgreSQL
- Webmin modules for configuring PostgreSQL.
- PostgreSQL is configured to listen on its default port on all interfaces by default, and accept connections from all hosts.
- PostgreSQL password encryption enabled by default (security).
- The Postgres user is trusted when connecting over local Unix sockets (convenience).

Featured companies Apple, Fujitsu, Red Hat, Cisco, Juniper Network, etc. are using built products and solutions using PostgreSQL.
No default passwords: For security reasons, there are no default passwords. All passwords are set at system initialization time.
