Note that this action must be done as root, or it will have no effect;

so a root-owned startup script is the easiest place to do it. If you

do this, you may also wish to build <productname>PostgreSQL</>

with <literal>-DLINUX_OOM_ADJ=0</> added to <varname>CFLAGS</>.

with <literal>-DLINUX_OOM_ADJ=0</> added to <varname>CPPFLAGS</>.

That will cause postmaster child processes to run with the normal

<varname>oom_adj</> value of zero, so that the OOM killer can still

target them at need.
