I was envisioning it as disabling all filesystem access --- read as well as write. Essentially the abstract concept I want is that with this on, even a superuser cannot use Postgres to get at the underlying operating system. A name like "enable_filesystem_access" would probably be more appropriate. Also, as I already said, marking it as PGC_POSTMASTER is simply not adequate security. Once we have some sort of remote admin feature, I would expect it to support adjustment of even postmaster-level options (this would mean forcing a database restart of course) --- you can hardly say that you have a complete remote admin solution if you can't change shared_buffers or max_connections. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
