We could also make it optional.
Silly point postgresql.conf has a bunch of settings that are needed by the server before it can actually read the database, Sure move out settings that are not needed early in startup but your going to get problems with others.
I quite like the function based method its flexible. Allowing pg_settings to be update able does not seam to be a bad idea but then you could do that with triggers and rules that called the functions surly?
set should be for temporary transaction and session based variables, not for change permanent things thats what the SQL constructs insert, update, alter, create, delete, drop etc are for.
