Hi Manu,
I think v7 is correct, but I am not sure it is better than v6.
v6 keeps the shortcut for both protocols. Its cost is that a
pipelined ALTER commits on its own, but I think few people send
SET TABLESPACE in a pipeline with other statements.
v7 changes no behavior, but the shortcut only helps simple protocol
clients. For me that means mostly psql.
I personally prefer v6, but that should be a committer decision.
Thanks,
Shihao
