14 years or less. Any version of Postgres before 9.0 was a nightmare to administer as a real production transactional dbms, at least the off the shelf version without a whole lot of tweaking without a (then very rare) pg expert.

I don't remember that. But I remember having basic DB features like transactions while MySQL didn't.

If say it was only about 15 years ago that the Postgres is slow stuff started dying off. Right around 2010.

It was definitely initially seen as big and cumbersome compared to MySQL, but sentiment shifted.

MySQL was kind of a fast toy database in the early days, but it was good enough to power simple PHP based websites.
