According to these slides from Sqlite founder, Sqlite was a "spin-off" of Postgres: http://www.pgcon.org/2014/schedule/attachments/319_PGCon2014OpeningKeynote.pdf http://www.pgcon.org/2014/schedule/attachments/319_PGCon2014... According to this, "SQLite was originally written from PostgreSQL 6.5 documentation" https://www.pgcon.org/2014/schedule/events/736.en.html https://www.pgcon.org/2014/schedule/events/736.en.html So, "fork" wasn't the right word. Apologies.
