Though I did learn the most while having a lot of data and had issues with performance.
Studying Postgres in that job was the absolute best part, I learned so much, and now I can't find a problem Postgres can't fix.
There was a running joke in my last office that I was paid to promote Pg because every time MySQL fucked something up, I would bring up how Postgres would solve it. I even did several presentations.
Then we migrated to Postgres and suddenly everything is stable as a rock, even under worse conditions and way more data.
