It's not an option *to* initdb, it's an option which is used *by*

That really did not clear things up:) Does it mean that you can
pre-populate the $DATA directory with a postgresql.conf that has
allow_system_table_mods set to on and initdb will pick it up?
Personally, I think tampering with the system catalogs is foolish. Still
if you have documentation for something(even if it is a foot gun) it
should be understandable. If the intent is for end users/dba's not use
these options I would say take then out of the user docs and put them in
the developer Wiki section.
I'm afraid I'm done with this particular discussion. Hopefully it's
purpose is now clear and you understand a bit better what is required to
actually add a column to pg_class.
Thanks!
