Per recent discussion, here is yet another updated version of the instrumentation patch. Changes:
* Added guc option "disable_remote_admin", that disables any write operations (write, unlink, rename) even for the superuser. Set as PGC_POSTMASTER so it cannot be changed remotely. I put this under "file locations", because that's where all the other config file information is. Though that doesn't feel completely right, I couldn't find a better place without creating a whole new category (it's not *connection* security, after all), and if that's to be done I think it's better if one of the committers pick name etc for it :-) * Make sure pg_file_stat() can only be used by superuser. It lacked this check previously. * Updated so it applies to current cvs. This means all oids have changed, since they were all used for other things now. Also added a required header that had moved with the datetime stuff. Actual code changes against the previous patch are very small. //Magnus
