Hello,
Some days ago I upgraded from 8.4 to 9.3, after the upgrade some queries
started performing a lot slower, the query I am using in this example is pasted

Hello all,
I am trying to simplify some of the queries I use with my database creating a
big view of all the possible attributes my items can have, the view is rather
large:

I thought that Postgresql would optimize out joins on columns I don't ask for
when I use

Hi all,
i am having any problems with performance of queries that uses CTE, can the

emp_id integer NOT NULL,
name character varying NOT NULL,
CONSTRAINT employee_pkey PRIMARY KEY

CTEs act as optimization fences. This is a feature, not a bug. Use
them when you want
