DROP COLLATION — remove a collation

Synopsis

+DROP COLLATION [ IF EXISTS ] name [ CASCADE | RESTRICT ]
+

+ DROP COLLATION removes a previously defined collation. + To be able to drop a collation, you must own the collation. +

IF EXISTS: + Do not throw an error if the collation does not exist. + A notice is issued in this case. +
name: + The name of the collation. The collation name can be + schema-qualified. +
CASCADE: + Automatically drop objects that depend on the collation, + and in turn all objects that depend on those objects + (see Section 5.14). +
RESTRICT: + Refuse to drop the collation if any objects depend on it. This + is the default. +

+ To drop the collation named german: +

+DROP COLLATION german;
+

+ The DROP COLLATION command conforms to the + SQL standard, apart from the IF + EXISTS option, which is a PostgreSQL extension. +
