Hi,

Please find attached v3 of the Extension Templates patch, with full
pg_dump support thanks to having merged default_full_version, appended
with some regression tests now that it's possible.

The patch also implements ALTER RENAME and OWNER facilities for those
new templates objects.

That's been fixed by merging in the default_full_version patch.

And that just works at pg_restore time, automatically, without pg_dump
having to know anything about how.
