Pavan Deolasee is a contributor to the development of PostgreSQL and related technologies. He holds a Masters of Technology in Computer Science from the Indian Institute of Technology, Bombay, and has several publications to his credit.

Pavan was introduced to PostgreSQL in the year 2006 when he started working for a PostgreSQL company. Hacking PostgreSQL was a completely new experience, but by accepting help from the community -- especially Simon Riggs, his mentor -- he began working through the code and was soon working on a very important project (Heap-Only-Tuple aka HOT). It was a very complicated piece of work, yet one of the landmark features in PostgreSQL and to this day remains one of his most important contributions to the project. Pavan has since contributed several patches to PostgreSQL. 

HOT was committed to PostgreSQL in 2008 and Pavan has continued to stay fully engaged with the project. In 2009/2010, alongside other colleagues, Pavan started work on Postgres-XC, a distributed, shared-nothing, clustering solution based on PostgreSQL. He was involved in designing the high-level architecture of the solution, and later wrote many important pieces of the code such as the GTM, the GTM Proxy, the 2PC transaction controller at the coordinator, changes required to guarantee global consistency of the data, and many distributed planner and executor pieces.

When Postgres-XL, a fork of Postgres-XC, was released to the public in 2014, Pavan once again became involved with the project and has been leading the development of Postgres-XL ever since. 

Pavan joined 2ndQuadrant not long after in April 2015, and once again started working with long time colleagues and friends; he and 2ndQuadrant have continued to actively work on the development of Postgres-XL. The focus area of development has been stability and performance of the product while keeping the fork as close to open source PostgreSQL as possible. The most recent release (Postgres-XL 10) supports intra-datanode query parallelism, thus taking distributed query processing to the next level.

In 2013, Pavan and two of his colleagues started the India PostgreSQL User Group. They started conducting small meet-ups, in order to promote the technology in India and bring the local community together. These small gatherings have now expanded with a membership of over 600 members, and into a full scale conference: PGConf India, Asia's largest PostgreSQL conference with more than 250 people in attendance each day in 2018. 

As part of the 2ndQuadrant team of PostgreSQL developers, Pavan continues to work on many interesting new features. He is an active part of the production support team and also has the opportunity to investigate interesting customer problems, often leading to important and critical bug fixes to the open source project.

Pavan had this to say about his involvement with the project:

“I love PostgreSQL and the PostgreSQL community, so you will continue to see me around.”
