OK, so I fixed that, and also updated the documentation a bit more. I
think these patches are basically done, and I'd like to get them
committed before too much more time goes by, because I have other
things that depend on this which I also want to get done for this
release. Anybody object?
I'm hoping not, because, while this is a behavior change, the current
state of play in this area is just terrible. To my knowledge, this is
the only place in the system where we allow a dangling OID reference
in a catalog table to persist after the object to which it refers has
been dropped. I believe it's also the object type where multiple
grants by different grantors aren't tracked separately, and where the
grantor need not themselves have the permission being granted. It
doesn't really look like any of these things were intentional behavior
so much as just ... nobody ever bothered to write the code to make it
work properly. I'm hoping the fact that I have now done that will be
viewed as a good thing, but maybe that won't turn out to be the case.
