Обсуждение: initdb problems on Solaris

Hi All,

I know that the whole "id" thing in initdb is a can of worms.
We have pg_id but we don't want to use it, every system has 
a different version/variety of whoami/"who am i"/id.

We don't need/want to use the unix ID of the user, but we do
when we can. The whole thing is a mess!!

One thing we need to do is change the default, "if all else
fails" id from 0 to something else, as 0 is specifically 
disallowed and causes an "Abort" in postgres when bootstrapping.

Here's a patch to set it to 1. ( failing any better suggestion)

Keith.

Actually, I see no reason why the superuser's Postgres ID number
shouldn't default to 0.  If there's code in there to reject that,
isn't it doing the wrong thing?

The postmaster and backend can and should refuse to run with an
effective Unix userid of 0 (root), but that doesn't mean that
a Postgres ID of 0 is insecure, does it?

Can you be more specific in regards to what doesn't work, what needs
fixing, etc.?

Peter - 
If you're going to look at the id for initdb, please consider the
NT port as well. This may be more of a problem with cygwin than pgsql,
but pg_id didn't work correctly, and I had to hack on the initdb script
to get it to to run, with a 6.5.3 install, recently.

Oh dear, I just wrote a new pg_id thingy that fulfills all my initdb
wishes (no id, not whoami vs 'who am i', no Solaris stupidities), but
what's now? How does NT/Cygwin handle it? Don't they have a geteuid()
function? Feel free to hack up pg_id to always return 42 in that case.
