Hi All,
I have attached my attempt at documenting the use of
hard disk storage by a postgres database. I'll point out
that I am still on the learning curve for postgres, and
my assumptions may well be completely wrong.
The main point I think that needs validation is whether
it is best to create a model of a database in order to get
an accurate estimate of the space needed.
TIA
Richard A Lough

That's pretty much it. If you want to know how much space something is
going to take, create it and look at it. I don't think we want to get
users involved into counting the bits of each piece of overhead that comes
with a database. That creates assumptions that are going to be hard to
overcome or change in the future.
