What's the reference point here? To my mind a lot of the advantages in Postgres are around it's mature tooling for backups and replication; autovacuum is more than sufficient for fairly complex workloads when it comes to data file maintenance, and really the only somewhat-sore point is horizontal scaling - but even there, a lot of the pain comes from there being multiple viable solutions in-the-wild, with none having decisive buy-in across the userbase, and as such no out-of-the-box solution in the standard DB (which is, happily, recognized by the developers and very much a focus of current development work).
But, I'm comparing with mostly MySQL(/it's myriad descendants) and the whole NoSQL ecosystem; for all I know the tools available for PG are hopelessly primitive for people coming from of Oracle/IBM/SQL Server/Ingres/Teradata(/others? I pretty regularly learn of new DBMS engines with shockingly large companies and engineering orgs behind that that I've just never heard of; I'm sure there's plenty more.)
