They tend to use the localsystem or networkservice accounts for most things, which don't have passwords. The reason we don't do that is that since the early days of 8.0 we've said we want to enable users to use the service account as if it were a regular account, so that they can do things like access network resources (useful for server-side copy for example). I wasn't overly convinced back then that that was necessary, and I'm still not now. I suppose we potentially could use the networkservice account by default, and let advanced users override that on the command line if they need to. Then remembering the password becomes their responsibility. -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
