OK. 0008 in the attached v37 patch set does it.

I agree with it but we haven't finalized public APIs yet. Can
we defer it after we finalize public APIs? (Proposed public
APIs exist in 0003, 0006 and 0007.)

And could someone help (take over if possible) writing a
document for this feature? I'm not good at writing a
document in English... 0009 in the attached v37 patch set
has a draft of it. It's based on existing documents in
doc/src/sgml/ and *.h.

0001-0007 aren't changed from v36 patch set.


Thanks,
