See the thread in which the feature was designed originally: http://archives.postgresql.org/pgsql-hackers/2010-01/msg00170.php The key point is that to get useful behavior, you need cooperation between both a root-privileged startup script and the PG executable. That tends to throw the problem into the domain of packagers, more than end users, and definitely puts a big crimp in the idea that run-time configuration of just half of the behavior could be helpful. So far, no Linux packagers have complained that the design is inadequate (a position that I also hold when wearing my red fedora) so I do not feel a need to complicate it further. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
