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, 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.

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.
