Removes a previously defined 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.
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 Database extension.
