I was planning to document postgresql.conf with little hints, enough to get one
started, drawing inspiration from lilo.conf of debian, which is beautiful to
say the least..
I haven't find enough time to do that. But I will do it.. But I don't know all
the parameters enough. Of course I will post a starter but any input would be
welcome.
Point is we should be able to say RTFC rather than RTFA as that would get a DBA
single place to look at. I agree that no amount of simplicity is enough but
still..:-)
