I want to know the pros and cons of Single DB For Each User Vs One DB for all users. Most of the queries in my application are user specific. Being the case, is it advised to go to single DB for each user? I want to use PostGres DB and doesnt want to move towards NOSQL. The advantage of creating one db per user 1.Smaller Tables 2. No Partioning and Join Issues 3. Helps horizontal scalablity as we can just add more servers when number of users increases. 4. May not need connection pooling as we can increase the connection and number of queries are related to one person per db will always be low ..read more

I've written a stored procedure in PL/Python which will insert data into a table but I need to get the id value of the row I've just inserted. I've read how to do this using psycopg2 but I'm using plpy object like below. I can't see how to get a connection object with psycopg2 inside a stored procedure, because I'm not going to hard code user names and passwords into a stored procedure. Just to stress the point this pl/python is in the stored procedure, it's not the python that calls the stored procedure. Python def insert_advert(json_data): plan = plpy.prepare("INSERT INTO tbl_advert (fld_o ..read more
