Bumped version number to enforce extension re-creation as the SQL has
been modified.
Current limitations:
- Check for namespace existence: on error temp objects are left around
- What happens to the indexes?
- Tests needed.
- Should the default be the GUC default_tablespace instead of pg_default?
This is actually an original pg_repack shortcoming, not a regression.
...not the other way around. This allows DROP EXTENSION ... CASCADE to
remove temporary directories, simplifying the cleanup procedure after an
error, and getting rid of the schema on uninstall.
