- It is a known fact that Cloud vendors attract a lot of migrations to PostgreSQL. Managed infrastructure, database migration tools combined with zero software license are the strongest reasons for increased migrations to cloud. However, cloud vendors may promote their DBaaS platforms much more than their capabilities with scalability. Customers may not be aware of some technical limitations th...
PostgreSQL supports a wide variety of indexes. While most of them are common in almost all the databases, there are some types of indexes that are more specific to PostgreSQL.
Once we know what type of Indexes are suitable for our requirement, should we create an index physically or can we use a hypothetical index that is imaginary to the Optimizer. If that is possible, are there any ext...
- PostgreSQL is an advanced open source database that is completely community driven. Continuous development and performance improvements while making it feature rich gave PostgreSQL a great market penetration. When a database server is deployed in production, it is important to achieve several 9's of availability. It starts with a replication setup that is stable and some tool that could manag...
- PostgreSQL implements MVCC in a slightly different way when compared to databases like Oracle, MySQL and others. In PostgreSQL, there is a different method for managing UNDO that requires a cleanup concept called vacuum. Over a period of time, PostgreSQL implemented autovacuum that has been enhanced with every release. It is now important for PostgreSQL admins/DevOPS to understand the interna...
- Optimizing a PostgreSQL database may be a challenge if some of the important parameters are ignored. And a bigger challenge may be the understanding of the algorithm behind setting those parameters correctly. In my experience with PostgreSQL Consulting for more than a decade, I have seen a bigger list of parameters that are wrongly set or ignored. This talk details a list of important Postgre...
- It is very important to know a fact that PostgreSQL community does not support bug fixes and security fixes for older PostgreSQL versions. Currently, community only supports PostgreSQL versions starting from 9.4. So, if your database server is on 9.3 or older, you would see no bug fixes or security patches. Several benchmarks proves that the performance of a PostgreSQL database increases with...

In the proposal, I would like to share how we have optimized a few database parameters that did outburst the performance by several times. It was a PostgreSQL Server of size 325 GB and more than 1500 TPS. After our tuning, we were able to get the database process upto 4900 TPS without compromising on ACID or availability.

- This tutorial is focused on teaching PostgreSQL to professionals that are already experienced with Oracle or MySQL. As we discuss from basics, even a beginner may adapt the concepts easily. Relational databases share a lot of similar concepts. You may find it easier if we help you relate the concepts of PostgreSQL with Oracle/MySQL. Thus, we would start with PostgreSQL A...
