Annual multi-track PostgreSQL ecosystem conference in Jinan, China, organised by Highgo Software around its Oracle-compatible PostgreSQL distribution IvorySQL; mostly Mandarin with an English/international track. Posted to postgresql.org events by Highgo. 'HOW' has been expanded as both 'Highgo Open World' and 'Hello Open-source World'. Highgo held an earlier 'HighGo Open World' event in April 2023, but no reliable source tying it (or any 2024 edition) to this conference was found, so only 2025 onward is recorded. YouTube is the IvorySQL channel.
