Adds `createDatabase` method to Postgres adapters which can be used
either independently like this:
```ts
payload.db.createDatabase({
name: "some-database",
schemaName: "custom-schema"
})
```
Or
```ts
payload.db.createDatabase()
```
Which creates a database from the current configuration, this is used in
`connect` if `autoDatabaseCreate` is set to `true` (default).
You can disable this behaviour with:
```ts
postgresAdapter({ autoDatabaseCreate: false })
```
