I may admit, I discussed mysql vs postgres at #FediCon a lot, it kinda went like this:

"one does not simply have problems with mysql

its uptime is guarded by more than just replicas. there is an innodb there that does not sleep, and the great eye of postgres is ever watchful. mostly watching its own autovacuum

pixelfed, loops and writefreely chose the path of peace.

zero incidents.

we simply do not know what downtime is"
