Of course not a nice regression but you should not run PostgreSQL on large servers without huge pages enabled so thud regression will only hurt people who have a bad configuration. That said I think these bad configurations are common out there, especially in containerized environments where the one running PostgreSQL may not have the ability to enable huge pages.
Surely they would be testing the configuration(s) that they use in production? They’re not running RDS without hugepages turned on, right?
