“does it all well” is a stretch.

Any non-trivial amount of data and you’ll run into non-trivial problems.

For example, some of our pg databases got into such state, that we had to write custom migration tool because we couldn’t copy data to new instance using standard tools. We had to re-write schema to using custom partitions because perf on built-in partitioning degrades as number of partitions gets high, and so on.
