[PATCH 0/5] Transactional DDL

[Vladimir Davydov]

This patch set implements transactional DDL for the case when all
statements are non-yielding. There are only two DDL statements that
may yield implicitly - building of a new index and checking a space
format - so it must cover most user stories. For more details re
the implementation, see comments to the individual patches.
