I was thinking about the following (increasinly common, I think)
use-case: we have a largish organisation where the platform/whatever
team wants to deploy Postgres in a uniform way and install the common
set of all contrib and external extensions that might be needed for each
instance. But then you have instance-specific admins that might want to
restrict the set of extensions their instance (or their developers/app
admins/whatever) is allowed to use. However, this is not the purpose of
the patch in discussion, just a side-remark that this functionality
would be good to have in addition.
