ALTER CONVERSION(7) PostgreSQL 16.2 Documentation ALTER CONVERSION(7)

ALTER_CONVERSION - change the definition of a conversion

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

ALTER CONVERSION changes the definition of a conversion.

You must own the conversion to use ALTER CONVERSION. To alter the owner, you must be able to SET ROLE to 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.)

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.

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;

There is no ALTER CONVERSION statement in the SQL standard.

CREATE CONVERSION (CREATE_CONVERSION(7)), DROP CONVERSION (DROP_CONVERSION(7))
