I find Magnus's approach to be admin un-friendly, and your patch a re-enforcement of that feeling. Forcing people to fall back on the OS tools (which may not be terribly good on systems like win32) when we could provide a consistent way for postgres to handle this itself seems backwards. I believe this would be much simpler for DBA's if we simply give them a GUC for stat file location, and allow them to set the location that way. Ideally this could be done as PGC_SIGHUP, and a change to the location would move the file "on-the-fly" as they say. (There might be practical limitation to making that work, but it would certainly be simpler for admins, imho) -- Robert Treat Build A Brighter LAMP :: Linux Apache {middleware} PostgreSQL -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
