Allow WITH clauses to be attached to INSERT, UPDATE, DELETE statements.
This is not the hoped-for facility of using INSERT/UPDATE/DELETE inside
a WITH, but rather the other way around. It seems useful in its own
right anyway.
Note: catversion bumped because, although the contents of stored rules
might look compatible, there's actually a subtle semantic change.
A single Query containing a WITH and INSERT...VALUES now represents
writing the WITH before the INSERT, not before the VALUES. While it's
not clear that that matters to anyone, it seems like a good idea to
have it cited in the git history for catversion.h.
Original patch by Marko Tiikkaja, with updating and cleanup by
Hitoshi Harada.
