The document discusses the history and current state of the Japan PostgreSQL Users Group (JPUG), a non-profit organization that promotes PostgreSQL usage in Japan. It describes how JPUG was founded 15 years ago after an active mailing list emerged in the late 1990s. Currently, JPUG focuses on providing PostgreSQL information, educating users through meetups, and connecting the community. It has over 50 members and 9 regional branches that hold conferences and events to advance PostgreSQL in Japan and connect with other Asian communities.
