my vague memories of ~2000 were that postgres was acknowledged as the way to go if you wanted to do it right, but mysql would let you get set up quickly and easily so you could get on with your actual application, and postgres had the reputation of being harder to set up and administer
Same memories here. In the late 90s I chose MySQL over Postgres, at the time for its speed and replication. And at least partly because I got to talk with Monty Widenius at an Open Source Conference (or perhaps even a Perl Conference) in the late 90s about replication, and asked how hard it'd be to make replication use SSL - and he sent me a beta MySQL version with that implemented a few days later. So I had a quite serious "feel good" reason for using MySQL. In the subsequent 5-10 years or so I regretted not choosing Postgres instead over it's stored procedure handling, but we had way to much deeply embedded MySQL tech and skill by then which made switching always end up on the too hard list.
