Thread: private table

Hello,
I am want to use a private table in postgresql(every client to see his own  
data).
Is this possible? How can I do it!

Thank you,
Adrian Din

Why?

You can create different users and/or different databases.

If I understand what you want, then this is traditionally done using views.

CREATE TABLE base_table (  a integer NOT NULL,  b text,  u name,  PRIMARY KEY (a)
);

CREATE VIEW my_rows AS  SELECT a,b FROM base_table WHERE u = CURRENT_USER;

Add rules so that updating my_rows updates base_table instead. Then, 
revoke access on base_table (apart from your super-user) but grant it on 
my_rows.

As far as a user is concerned "my_rows" just contains their rows and if 
they log in as a different user they will see different data.
