Launching the PGNexus Platform, Building a New Hub for Global Collaboration.
During the conference, the PGNexus global collaboration platform (https://pgnexus.ai/) was officially launched. Guided by the philosophy of “Code as a Bridge, Inspiration as a Medium,” the platform aims to build an open, inclusive, and efficient global collaboration network, breaking down geographical and organizational boundaries to connect PostgreSQL developers, enterprise users, and contributors worldwide. Through intelligent collaboration tools and resource-sharing mechanisms, it seeks to drive a new pattern of globally linked open source collaboration.
Currently, open source has become the core paradigm for global software technology and industrial innovation. The successful hosting of the HOW2026 China Database Open Source Development Summit and PostgreSQL High-Level Forum comprehensively showcased the innovative vitality of open source databases represented by PostgreSQL in the AI era, conveyed the voice of China’s open source industry gaining momentum, and established a high-energy platform for in-depth global database technology exchange and collaborative innovation. Looking ahead, we will uphold the original intention of “Connecting the World with Open Source,” deeply cultivate the ecosystem, accelerate the integration of technology and industry, and join hands with global developers to contribute to building a new, open, and win-win global open source landscape.
