DROP COLLATION

remove a collation

DROP COLLATION \[ IF EXISTS \]

name

\[ CASCADE \| RESTRICT \]

Description {#sql-dropcollation-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 [???](#ddl-depend)).

`RESTRICT`

:   Refuse to drop the collation if any objects depend on it. This is
    the default.

Examples {#sql-dropcollation-examples}
========

To drop the collation named `german`:

    DROP COLLATION german;

Compatibility {#sql-dropcollation-compat}
=============

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