# 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 | CURRENT_USER | SESSION_USER }
    ALTER CONVERSION name SET SCHEMA new_schema

## Description

`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.
