Yeah, but I don't need advice on installing PG on that ;-). In general,
I think the filter rule could be: is it likely that someone would try to
install PG 13-or-later from scratch (with no pre-existing installation)
on this OS version? If there is a pre-existing install, they'll already
have dealt with any kernel configuration issues.

So I concur with dropping all this stuff, and while we're at it I'd vote
for getting rid of the oom_adj para. RHEL6 will be fully EOL around the
time PG13 comes out, so I don't believe anyone's making brand new installs
there either.
