Thomas,
Thank for your response may put this way.
Hello all,
Good day.
I have the following scenario.
System 1:
Database: postgresql 8.4
application server: tomcat 6
System 2:
Database: Postgresql 8.4
Application Server: Tomcat 6:
These system to be able to exchange data.
Then I would like to install it to use one postgresql 8.4 and one tomcat 6.all these run on the same machine but different system.
Is it possible?
Please any help appreciated

You will need to setup schemas and corresponding users to achieve this:
First you need to create three different users.
Then for each user create one schema and make the corresponding user the owner of the schema.
Set the user's search path such that their "own" schema is the only one in the list (or at least the first one).
That way the application users don't have to prefix all tables.
Something like this:
create user u1 password 'welcome';
create user u2 password 'welcome';
create user u3 password 'welcome';
create schema s1 authorization u1;
create schema s2 authorization u2;
create schema s3 authorization u3;
alter user u1 set search_path to s1;
alter user u2 set search_path to s2;
alter user u3 set search_path to s3;
commit;
For those tables that need to be used by more than one user (i.e. application) grant the necessary privileges to the other users.

Thomas
