My reading was less that PostgreSQL was "too difficult to use" and more that MySQL is less strict about safety. That difference is more substantial than it may sound. "An ounce of prevention is worth a pound of cure", as they say. While PostgreSQL may do things in a way that require a little extra annoyance up front, they're usually that way to prevent disastrous data integrity issues further down the line. What can you say when someone says things like "We prefer logical replication because it uses less bandwidth"? There are extremely good justifications for the high bandwidth cost of real (bit-level) replication. Logical replication has uses but IMO it should be applied cautiously and sparingly. I felt all of the ASCII shrugs were justified. They signify a tradeoff that Uber made. My personal feeling is that most of those tradeoffs were bad, but what can you do. The slides shrug because you can't argue. If that's the problemset that their organization prefers to deal with, more power to them.
