How To Install & Configure PostgreSQL?

POSTGREES 4.2 is the foundation for PostgreSQL, a common database management system. PostgreSQL is built to work on a variety of operating systems, including Windows and Solaris. It is open-source, free program that allows you to alter PostgreSQL in any way. PostgreSQL was first designed to work on UNIX-like systems, and then it was made to be portable. Its stability means that controlling it requires less work. Compared to other database management systems, PostgreSQL is inexpensive to use for developing online applications.

PostgreSQL Features

• Portable
• Stable
• Affordable
• Extensible
• User-defined types
• Table inheritance
• Sophisticated locking system
• Foreign key referential integrity
• Views, rules, sub-query
• Nested transactions (save points)
• Multi-version concurrency control (MVCC)
• Asynchronous replication

The multi-version concurrency feature (MVCC) is a feature of PostgreSQL. In Oracle, the MVCC capability is sometimes referred to as snapshot isolation. One other important aspect of PostgreSQL is that it allows you to add custom functions using a variety of programming languages, such as Java, C/C++, and so on. You may specify the data types, index types, functional languages, and other elements in PostgreSQL. Additionally, you may make a custom plugin to improve it to meet your needs. If you require a database for a robust backend application and are searching for robust security, compliance, and stored procedures, PostgreSQL is a good choice. MySQL is a viable choice for those seeking a more global platform, enhanced security features, and a preference for working with content management systems.

PostgreSQL utilizes a client/server architecture. The PostgreSQL server has the ability to handle several client connections at once. With tight connection between the storage engine and the remainder of the database, it supports a single storage engine. To accommodate more data in the allocated disk space, PostgreSQL has the ability to quickly compress and decompress its data using a fast compression algorithm. In addition to reducing disk space, compressed data has the advantage of requiring less input/output (IO) when reading, which leads to quicker data readings. PostgreSQL is compatible with a variety of computer languages and operating systems, including C, C++, Java, Perl, Python, and Ruby.

Tools For Managing PostgreSQL

1. pssql: This is the primary command line tool for managing PostgreSQL.
2. phpPgAdmin: This is a web based administration tool for PostgreSQL created in PHP.
3. pgFouine: This is a log analyzer tool that creates reports from PostgreSQL log files.

Steps For Installing & Configuring PostgreSQL

• Run – /scripts/installpostgreSQL command.

• Go to ‘Configure PostgreSQL Interface’ (Home >> SQL Services >> Configure PostgreSQL).

• For installing PostgreSQL, click on ‘Install Config’.

• For adding current cPanel users to PostgreSQL, click on ‘Create Users’.

• Enter the password in the ‘Enter New Password’ section, re-enter it in the ‘Confirm Password’ section.

• When you have entered the password, click on ‘Change Password’.

To Restart PostgreSQL

• Click on ‘SQL Server (PgSQL)’ under ‘Restart Services’.

Execute this command for editing the PostgreSQL Confirmation file:

• vim /var/lib/pgsql/data/postgresql.conf file.

Benefits Of PostgreSQL

• It is open-source and standard compliant RDBMS
• Backed with a powerful community
• Provides third-party support
• Stored procedures
• Extensible
• Object-oriented

Disadvantages Of PostgreSQL

• Struggles with big read-heavy operations against a database
• Less popular
• Low open-source documentation and collaboration
• Uses a different SQL syntax as compared to the traditional MySQL/Microsoft SQL solutions
