I don't understand why this comment is down voted. I've been part of a project that uses a dozen different PostgreSQL databases from different services, one of those databases is multi TB with an OLAP usage patterns. And it beats performance-wise all the previous attempts to solve that specific problem.

Postgres is the Post-Ingres database. Originally it used QUEL (as in PostQUEL as in libpq) as a query language. When SQL support was added the product name was changed to PostgreSQL

Postgree isn’t a thing.

Postgres or PostgreSQL are acceptable. Postgre or postgree are not.
