pg_config : postgresql.conf adjustments?

Hi all,

Would it be beneficial for us to extend "pg_config" to update the
postgresql.conf file?

i.e.

pg_config --sort_mem 16384 --shared_buffers 800

pg_config -d /some/datadir --sort_mem 16384 --shared_buffers 800

etc?

Not sure if it should trigger a restart of postmaster, etc, but the
concept sounds useful.

:-)

Regards and best wishes,

Justin Clift
