When commenting on a column, relation_name must refer to a table, view, composite type, or foreign table. SQL allows triggers to fire on updates to specific columns; As of version 9.0 of PostgreSQL this feature is also implemented in PostgreSQL.

WHEN FOR EACH STATEMENT1 PostgreSQL Triggers are database callback functions, which are automatically performed/invoked when a specified database event occurs.. Performing conditional actions in triggers (or testing data following modification) is done through accessing the temporary Inserted and Deleted tables. When using these options you need to keep a few things in mind. Examples: DECLARE prior ALIAS FOR old; updated ALIAS FOR new; Since ALIAS creates two different ways to name the same object, unrestricted use can be confusing. So, for instance, the information_schema.tables table lists all the tables in the database and their attributes (such as being able to see whether it is a table or a view, what the name is and other information like that).
