Absolutely don't agree. Sure, Mysql mostly became very popular with the rise of PHP in the early 2000's, but Postgres was popular in many less visible industries. In my 'world', MySQL was seen as an amateur database engine, and never really lost that label. There was some serious hesitation towards Postgres back-then, but eventually it became a good alternative to the commercial RDBMS's. I know we eventually switched everything over. Until the mid 2000's - our server-side software was still sold as a 'blackbox', managed by us, with no mention of it running linux and postgres, but eventually these became more accepted technologies, and towards many of our clients even a selling point. The rise of Redhat in the enterpricy world helped a lot with that.
