overcommit_ratio setting

[Yi Sun <yinan81@xxxxxxxxx>]

Hello,

After checking doc, only mentioned vm.overcommit_memory=2, but didn't mentioned vm.overcommit_ratio recommended value

https://www.postgresql.org/docs/11/kernel-resources.html#LINUX-MEMORY-OVERCOMMIT

some articles mentioned that 80 or 90 configuration in their env

So is it OK just to configure  vm.overcommit_ratio to 90 please?

Thank you
