The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/18/kernel-resources.html
Description:
18.4. Kernel Resource Management
In this section:
1) Table 18.1. System V IPC Parameters
> SEMMAP > “see text” -- what does this mean?
2) in the Linux section:
block
$ sysctl -w kernel.shmmax=17179869184
$ sysctl -w kernel.shmall=4194304
$ replace with #
> To make these settings persist over reboots, see /etc/sysctl.conf.
replace “see” with “modify”
3) Global changes in the section:
you continue to use the server process name as “postmaster”!!! way too many
times (find and replace it)
