ALTER CONVERSION
Changes 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 does not do anything you could not do by dropping and recreating the conversion. However, a superuser can always alter ownership of any conversion.).
Parameters
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.
