macOS Catalina - postgreSQL - sysctl.conf still relevant?

Database Administrators Asked by Crashmeister on January 4, 2022

I had the following settings in /etc/sysctl.conf before Catalina:

# PostgreSQL Config for the MAC

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?

I ran into the same issue. I put the file back (at /etc/sysctl.conf) and it worked just like before (at least for setting kern.maxvnodes).

You don't need the shared memory parameters any more, because PostgreSQL has been using POSIX shared memory for a while now.

Making sure that the PostgreSQL user can have enough open files is a good idea though.
