I think disabling ALTER SYSTEM can be more easily supported if we
choose one of below options:
a. UI into contrib module, people who don't want doesn't include it
b. Have an include file mechanism, so that user can comment the
include in postgresql.conf and disable it.
If I remember correctly, earlier you mentioned that by default auto
file should be parsed after postgresql.conf, but how about reverting
to previous mechanism of "include" such that if the file is mentioned
in include then it will be parsed, else will be ignored. I think this
can be reasonable way to disable.
