Infer Type from PgEnum

Hey, I'd like to infer a PgEnum to a TypeScript Type. So something like this:

const eventTypeEnum = pgEnum('event_type', [
    'training',
    'matchday',
    'tournament',
    'event',
    'labour'
]);

// get the following as a result
type EventType = 'training' | 'matchday' | 'tournament' | 'event' | 'labour'

const eventTypeEnum = pgEnum('event_type', [
    'training',
    'matchday',
    'tournament',
    'event',
    'labour'
]);

// get the following as a result
type EventType = 'training' | 'matchday' | 'tournament' | 'event' | 'labour'

How could I achieve this?

you can do something like this i guess?

const EVENTS = ['training', /*...*/] as const;
const eventTypeEnum = pgEnum('event_type', EVENTS);
type EventType = typeof EVENTS[number];

const EVENTS = ['training', /*...*/] as const;
const eventTypeEnum = pgEnum('event_type', EVENTS);
type EventType = typeof EVENTS[number];
