NAME

       ALTER_COLLATION - change the definition of a collation

SYNOPSIS

       ALTER COLLATION name RENAME TO new_name
       ALTER COLLATION name OWNER TO { new_owner | CURRENT_USER | SESSION_USER }
       ALTER COLLATION name SET SCHEMA new_schema

DESCRIPTION

       ALTER COLLATION changes the definition of a collation.

       You must own the collation to use ALTER COLLATION. To alter the owner, you must also be a
       direct or indirect member of the new owning role, and that role must have CREATE privilege
       on the collation's schema. (These restrictions enforce that altering the owner doesn't do
       anything you couldn't do by dropping and recreating the collation. However, a superuser
       can alter ownership of any collation anyway.)

PARAMETERS

       name
           The name (optionally schema-qualified) of an existing collation.

       new_name
           The new name of the collation.

       new_owner
           The new owner of the collation.

       new_schema
           The new schema for the collation.

EXAMPLES

       To rename the collation de_DE to german:

           ALTER COLLATION "de_DE" RENAME TO german;

       To change the owner of the collation en_US to joe:

           ALTER COLLATION "en_US" OWNER TO joe;

COMPATIBILITY

       There is no ALTER COLLATION statement in the SQL standard.
