ALTER CONVERSION
Changes the definition of a conversion.
Synopsis
ALTER CONVERSION <name> RENAME TO <newname>
ALTER CONVERSION <name> OWNER TO <newowner>
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 the 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.
