Something that might be handy would be a method to determine if an
object is a system object or not (perhaps what the OP means by
bootstrap). We spent quite some time figuring out how to handle that
when we were working on newsysviews. In that case, we wanted the info
because it's handy to be able to query a view that's not cluttered up
with a bunch of system-defined stuff. Having a way to get a list of only
user-defined functions, for example.
