NAME¶

ALTER_COLLATION - change the definition of a collation

SYNOPSIS¶

ALTER COLLATION name RENAME TO new_name
ALTER COLLATION name OWNER TO new_owner
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

new_name

new_owner

new_schema

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.
