ALTER CONVERSION

Name

ALTER CONVERSION -- change the definition of a conversion

Synopsis

ALTER CONVERSION name RENAME TO new_name
ALTER CONVERSION name OWNER TO new_owner
ALTER CONVERSION name SET SCHEMA new_schema

Description

Note: The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

ALTER CONVERSION changes the definition of a conversion.

You must own the conversion to use ALTER CONVERSION. 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 conversion's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the conversion. However, a superuser can alter ownership of any conversion anyway.)

Parameters

name

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

new_name

The new name of the conversion.

new_owner

The new owner of the conversion.

new_schema

The new schema for the conversion.

Examples

To rename the conversion iso_8859_1_to_utf8 to latin1_to_unicode: 

ALTER CONVERSION iso_8859_1_to_utf8 RENAME TO latin1_to_unicode;

To change the owner of the conversion iso_8859_1_to_utf8 to joe: 

ALTER CONVERSION iso_8859_1_to_utf8 OWNER TO joe;

Compatibility

There is no ALTER CONVERSION statement in the SQL standard.
