DROP COLLATION(7)       PostgreSQL 9.5.0 Documentation       DROP COLLATION(7)

NAME
       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.

       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.
