No, it's not currently possible to GRANT access to objects that don't
exist in PG.  This isn't a bug, as for if it's a possible future
feature, maybe (there's a current patch that I'm working on to GRANT
things like 'read only' or 'write only' access to all tables/views/etc),
but I don't expect to ever support the ability for GRANT to explicitly
name an object that doesn't exist yet (seems like it'd be rather
concerning too, because what if someone *else* created that database?
Suddenly this user has access to it?  No, thanks).

This hasn't ever worked in PG, so it seems a little curious that it's
the cause for PG support to be dropped.  Still, it's definitely not a
bug and certainly wouldn't be added to existing releases.  If you're
interested in following the development of PG, I'd suggest you take a
look at the -hackers mailing list.

Thanks,
