pg_dump does not include database-level user-defined GUC variables?

[Abelard Hoffman <abelardhoffman@xxxxxxxxx>]

I have a user-defined GUC variable that was set at the db level. e.g.,

  ALTER DATABASE mydb SET myapp.user_id TO '1'

Works fine. When I do a pg_dump, however, that variable isn't included.

Is that expected? It's not really an attribute of the database?

Thanks.
