Just listening in on this thread.... I would be inclined to agree that
the Win32 PostgeSQL should run under its own user given the history of
Windows security. FWIW I know that Installshield (one of the most
popular installers) and the default settings for MSI mean that only
administrators can install software; so I would argue that there is no
reason why the PostgreSQL installer also shouldn't require administrator
privilege to run, and therefore create the postgres user account for us.
I think that most of the services installed under Win32 use a separate
username and password. The last installer I used that required a
username and password was for a backup service and then it was simply a
page in the installer that asked for a username and password to run
under; both of these were set to defaults so all I had to do was click
"Next" and the account was generated for me and the directory
permissions set up correctly. This has the balance that the novice user
will just click "Next" while the advanced user can set up a customised
account to meet his/her needs.
In the case of a stand-alone executable, I can see things being a little
more tricky; however I don't see there being any reason why when we
launch the backend we try the default username and password (postgres
and "") and if that doesn't work then we ask for a new username and
password from the user. I would see that this wouldn't be done in the
backend but in the equivalent of the /etc/init.d/postgresql script under
Win32. If people really got upset about asking for the account password
on startup then I guess they would have to go for the service
installation - I see this as being no different to the inconvenience of
asking for a PEM passphrase when we restart Apache on our Linux servers.
Finally I believe we can tighten up security from SMB/RPC-based exploits
by applying the "can only logon locally" policy to the postgres account
which means that SMB/RPC connections cannot be made with the default
PostgreSQL username and password which is always a good thing :)
