There is a postgres user account on my OSX system. I'm not clear about how it was created. I've installed a binary version of 8.3 in /Library/PostgreSQL/8.3/ and built another version from source into /usr/local/pgsql/. When I login as root and then 'su - postgres' it takes me to the postgres account and the user directory is at /opt/local/var/db/postgresql83/. Can someone explain how this user account was created? I'm trying to start the server that I built from source but it will not create a logfile, ie: elegans:~ postgres$ /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start server starting sh: logfile: Permission denied elegans:~ postgres$ elegans:~ postgres$ nohup /usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data </dev/null >>server.log 2>&1 </dev/null & [1] 28696 elegans:~ postgres$ -sh: server.log: Permission denied elegans:~ postgres$ elegans:~ postgres$ pwd /opt/local/var/db/postgresql83 elegans:~ postgres$ elegans:~ postgres$ ls -al .. total 0 drwxr-xr-x 4 root admin 136 Aug 28 12:05 . drwxr-xr-x 8 root admin 272 Sep 9 14:49 .. drwxr-xr-x 3 root admin 102 Aug 28 12:05 postgresql83 drwxr-xr-x 3 root admin 102 Aug 26 13:06 smb Should I remove this user somehow and replace it with a standard user (using the system admin GUI)? Thanks, Darren
