Wait a minute. I haven't bought into either of those statements, and
most particularly not the first one.
Upthread, Dimitri claimed that he wasn't creating two different kinds of
extensions with this patch, but the more I read about it the more it
seems that he *is* making a fundamentally different kind of animal.
And I don't think it's necessarily a good idea, especially not if we
still call it an extension.
I kind of like Heikki's idea of leaving CREATE EXTENSION alone and
inventing a separate "UPLOAD EXTENSION" operation, but there's a problem
with that: in many, probably most, installations, the server does not
and should not have permission to scribble on the directories where the
extension scripts are stored. Possibly we could circumvent that by
creating an auxiliary extensions directory under $PGDATA. (But then
it starts to seem like pg_dumpall --- not pg_dump --- ought to include
those files in its output...)
