The PostgreSQL rule system allows one to define an alternate action to be performed on insertions, updates, or deletions in database tables. Roughly speaking, a rule causes additional commands to be executed when a given command on a given table is executed.
Note: You must be the owner of a table to create or change rules for it.
Rules are managed on the Rules tab of the Table Designer. Just simply click/double-click a rule field for editing. Using the toolbar below, allowing you to create new, edit and delete the selected rule field.
