Pushed with some mostly-cosmetic adjustments (in particular I tried
to make the docs and tests neater).

I did not commit the changes in get_available_versions_for_extension
to add no_relocate as an output column.  Those were dead code because
you hadn't done anything to connect them up to an actual output parameter
of pg_available_extension_versions().  While I'm not necessarily averse
to making the no_relocate values visible somehow, I'm not convinced that
pg_available_extension_versions should be the place to do it.  ISTM what's
relevant is the no_relocate values of *installed* extensions, not those of
potentially-installable extensions.  If we had a view over pg_extension
then that might be a place to add this, but we don't.  On the whole it
didn't seem important enough to pursue, so I just left it out.
