A Follow up on Key PostgreSQL Configuration Parameters for Enhanced Performance – Part 2

In a previous blog post, we configured an EC2 instance and installed PostgreSQL on it. After the initial setup, we ran pgbench to measure the initial TPS (transactions per second). Then, we tuned PostgreSQL and reran pgbench to see how much we could improve the TPS. To tune PostgreSQL, we adjusted various parameters based on the system's available resources. In this blog, we will identify which of those parameters contributed the most to the performance improvements. We will use the same instance size on AWS EC2 as before, which is t2.large. Here is the list of parameters that we initially tuned...

Guide to Auditing and Monitoring Access in PostgreSQL

In the data-driven world of today, maintaining the security and integrity of your database is paramount. Auditing and monitoring access to your database are critical components of an effective security strategy. These processes help ensure that only authorized users are accessing sensitive information and that any unauthorized access attempts are detected and addressed promptly. PostgreSQL is renowned for its robustness, extensibility, and adherence to standards. It offers a rich set of features for auditing and monitoring, which can be leveraged to enhance security and compliance. Purpose and Scope of the Blog: This blog aims to provide an in-depth guide on auditing and monitoring access in PostgreSQL. We will explore various tools, techniques, and best practices to help you implement effective auditing and monitoring strategies in your PostgreSQL environment.

Access Controls in PostgreSQL

Access control is a fundamental aspect of database security, ensuring that only authorized users can perform specific actions on the data. Effective access control helps protect sensitive information from unauthorized access and prevents data breaches, which can have severe legal and financial repercussions for organizations. PostgreSQL has a strong reputation for reliability, feature robustness, and performance. One of its notable strengths is its comprehensive support for various access control mechanisms, which allow database administrators to finely tune who can access what data and how.
