Well, any such setup is a serious security hole in itself, because there is likely to be sensitive data in the postmaster log, eg passwords. (Remember that the log file is global to the whole cluster, it will not contain just data relevant to the current session.) You should only grant access to people who you trust at more or less the level of trust you'd put in the installation DBA. It may be that these concerns are all irrelevant to you because it's a single-user installation anyway, but they're not irrelevant to people running multi-user installations. So that's why you can't get Postgres to do it. In a single-user installation, maybe you should just launch the postmaster as that user. regards, tom lane
