With transparent huge pages maybe it would be automatic. Seems 9.4 is able to handle it but it must be globally enabled using sysctl.

It seems to be clear we should disable transparent huge pages for all workloads:

Also recommended by PG doc.

Setting huge pages manually and adapting over time might be a pain though.
