My guess is that a whole lot (I'd go as far as to say most) users don't
do this. Instead they start the system in whatever is default, *and
think it's secure enough*. Therefor, the default should be a reasonable
guess at the securest thing they want. And setting "trust" is not that.
Sort of like MSSQL permitting and defaulting to a blank sa password in
earlier versions. Even MS fixed that. Yes, it took a worm for them to do
it, but they did...
If you want to fix that the whole way, install a pg_hba.conf *without
anything*. That way nobody can connect and use their database until they
(Turns out that is the same thing my patch does except it lets you set
it on the commandline to initdb instead of having to edit the file
assuming you just want local auth)

Oh, you mean along the line of having to create a separate user account
to run it under? I'd say that is a whole lot more work than just
entering a password. Or *explicitly* chosing that you want trust
This very argument was shot down pretty quickly last time it came up in
just a slightly different context, but it keeps popping up...

My thoughts exactly. Because most users *will not* edit pg_hba.conf
until they need it to enable something, this is a problem.

Um. No. initdb does not start the database. You're safe until you start
postmaster. This is defence against the fact that most users will start
the database without editing (or looking at, or for that matter even be
aware of the existance of) pg_hba.conf.

I say that warning should be in the form of "if you realy want this,
append --trust to the command you just issued", but any step towards it
is a step in the right direction :-)
