Free one-day, single-track community event about developing Postgres extensions, run by the Postgres Extension Developers Coalition with its own (free, Eventbrite) registration. The first edition (Montréal, 12 May 2025) was held at Plaza Centre-Ville the day before PGConf.dev 2025 at the same venue, but the site states it is 'not affiliated with other events'. Recognised under the PostgreSQL community event guidelines. For 2026 Postgres Conference (PostgresConf) ran an 'Extensions Day' (23 April 2026, San Jose) as one day of Postgres Conference 2026, sold through that conference's tickets and billed as bringing 'the Montreal format' west; it is treated as part of the postgres-conference series, not as an edition here. No separate social accounts found; other_social is the coalition's GitHub org.
