ALTER CONVERSION — change the definition of a conversion
ALTER CONVERSIONnameRENAME TOnew_nameALTER CONVERSIONnameOWNER TO {new_owner| CURRENT_USER | SESSION_USER } ALTER CONVERSIONnameSET SCHEMAnew_schema
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.)
nameThe name (optionally schema-qualified) of an existing conversion.
new_nameThe new name of the conversion.
new_ownerThe new owner of the conversion.
new_schemaThe 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.
