Hello,
1) To store tables in different locations use different tablespaces,
witch can be stored in different locations in your hard drive. Same goes
for the databases.
2)
a) Postgresql is fine data base management system, so I see no reasons
why you should not use it.
b) I'm not sure I fully understand you on that one. You want to
estimate, that after inserting some record into your database it will
reach your maximum size? Any way I don't know how to do this...

Hi, all
I have several questions to bother you. :)
1 For postgresql, is it POSSIBLE to store different tables in
different locations where we specify? For one postgresql management
process,
is it POSSIBLE to store different database in differentlocations
where we specify?
2 Is it appropriate to use Postgresql to store data for the following
situation:
The whole system consists of about 400 machines and I have to develop
a program collecting the information about capacity and performance
and networt setting and so on of each machines and displaying them for
the administrators and some related guys. Moreover, I have to store
some history data to display graphes
and curvers. My design is as follows: one daemon process running on
each machine to collect data and send it to the database which is in
one specified machine.
The bad thing is that the size of database is asked to be resricted in
900MB for some reasons.
The questions are:
(a) Is it appropriate to use postgresql database in this case? If not,
any sugguestion will be appreciated.
In fact considered using common file to store data. but you know,
it is possible that daemon processes on other 399 machines send data
simultaneously, ...
(b) It seems hard to estimate the maximum size of the database,
because frequently updating and inserting opreations will cause unused
space not acclaiming in time and we have to routinely vaccum.
Is there any good and easy, :) way to estimate the maximum size of
postgresql database accurately?
Best regards,
Duan
