12.3 ALTER CONVERSION

Name

ALTER CONVERSION -- change the definition of a conversion

Synopsis

ALTER CONVERSION name RENAME TO newname
ALTER CONVERSION name OWNER TO newowner

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.
newname
The new name of the conversion.
newowner
The new owner of 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.
