I think this is really a content-free argument. An outside-the-database
cron substitute would have to have superuser privileges so that it could
do SET SESSION AUTHORIZATION, but so what? If the DBA doesn't want to
cooperate in setting up a scheduler, he probably doesn't want his users
to use an inside-the-database one either.
There aren't really any permissions or security issues here that
weren't solved long ago. People have been using cron jobs driving
connect-as-superuser scripts to do periodic pg_dump and vacuum
maintenance since forever. An outside-the-database scheduler for user
tasks is a straightforward increment on that.
