Unhappy System tables : pg_class,pg_attribute
hey all,
I have added an attribute to pg_class system table and that attribute is visible in pg_class when i run 'select * from pg_class' but it is not visible in pg_attribute.
Each & every attribute of every relation is entered in pg_attibute table. So all attributes of pg_class are visible in pg_attribute except the one i have entered.
Can anyone help me ?? Plz reply asap.
Regards,
Aditi

The only way to add columns (=attributes) to a table is by using ALTER TABLE.

Messing with the system catalogs is begging for trouble.
