Hi all,

I start working with enumerator types and I am wondering, if my enumerator ca= n later be adjusted. E.g. if I would like to add another label.

Is it allowed just to add another entry to pg_enum? How is the enumerator then sorted (i.e. enum_last() )?

Is it possible to alter the labels of an enumerator later on? Can I edit pg_en= um?

Thanks already,

Andreas Gaab

E.g. if I would like to add another label. AFAIK you can't. Each enum is a own type. Use a lookup-table instead and use enum's only for real static things.
