DROP COLLATION
remove a collation
Synopsis
DROP COLLATION [ IF EXISTS ] NAME [ CASCADE | RESTRICT ]
Description
DROP COLLATION removes a previously defined collation. To be able to drop a collation, you must own the collation.
Parameters
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 Dependency Tracking).
RESTRICT- Refuse to drop the collation if any objects depend on it. This is the default.
Examples
To drop the collation named german:
DROP COLLATION german;
Compatibility
The DROP COLLATION command conforms to the SQL standard, apart from the IF EXISTS option, which is a PostgreSQL extension.
