+# this is the exhaustive list of types of comment:
+#COMMENT ON DATABASE my_database IS 'Development Database';
+#COMMENT ON INDEX my_index IS 'Enforces uniqueness on employee id';
+#COMMENT ON RULE my_rule IS 'Logs UPDATES of employee records';
+#COMMENT ON SEQUENCE my_sequence IS 'Used to generate primary keys';
+#COMMENT ON TABLE my_table IS 'Employee Information';
+#COMMENT ON TYPE my_type IS 'Complex Number support';
+#COMMENT ON VIEW my_view IS 'View of departmental costs';
+#COMMENT ON COLUMN my_table.my_field IS 'Employee ID number';
+#COMMENT ON TRIGGER my_trigger ON my_table IS 'Used for R.I.';
