<div class="diff add">+
+ SQL92 specifies some additional capabilities for
+ DROP VIEW:
+
+
+
+ DROP VIEW view {RESTRICT | CASCADE}
+
+
+
+ RESTRICT
+
+ Ensures that only a view with no dependent views or
+ integrity constraints can be destroyed.
+
+
+
+
+ CASCADE
+
+ Any referencing views and integrity constraints
+ will be dropped as well.
+
+
+
+
+
+ At present, to remove a referenced view from a PostgreSQL database,
+ you must drop it by hand.
