The started worker isn't associated with the original database. You can pass the database oid as an argument to the launched bgworker.
Thank you, this makes sense. However, how can this be done since I can only pass one argument to bgw_main? Is there any way to do this without having to store the value in shared memory? I was going to try passing an array instead of an int, but I'm not liking that much. I am trying to pass naptime and database_name (or oid).
