But Lucee is a Swiss company, so why aren't European companies interesting? I know that Zalando (European online clothing shop) uses Postgres (they have published several tools around it) and the German online tax system uses Postgres (there was a presentation by Alva Freude on the migration from Oracle a few years ago) I also found these pages: https://enlyft.com/tech/products/postgresql https://siftery.com/postgresql https://stackshare.io/postgresql https://www.builtincolorado.com/companies/tech/postgresql-companies-colorado https://www.builtinnyc.com/companies/tech/postgresql-companies-nyc but I don't know how credible those source are. Wikipedia lists some names: https://en.wikipedia.org/wiki/PostgreSQL#Notable_users including the International Space Station ;) Other Postgres support companies have also published some customer names: https://www.enterprisedb.com/customers https://www.cybertec-postgresql.com/en/postgresql-overview/solutions-who-uses-postgresql/
