macOS Catalina - postgreSQL - sysctl.conf still relevant?

I had the following settings in /etc/sysctl.conf before Catalina: # PostgreSQL Config for the MAC kern.sysv.shmmax=2147483648 kern.sysv.shmall=524288 kern.sysv.shmmin=1 kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.maxprocperuid=1024 kern.maxproc=2048 The Catalina install moved this file to the /Users/Shared folder as /etc is now considered private to macOS. Are these settings still relevant for Catalina, and if so, where do they need to go? Thx.
