I have committed your version v33.  I did another pass over the 
identifier and literal quoting.  I added quoting for replication slot 
names, for example, even though they can only contain a restricted set 
of characters, but it felt better to be defensive there.

I'm happy to entertain follow-up patches on some of the details like 
option naming that were still being discussed.  I just wanted to get the 
main functionality in in good time.  We can fine-tune the rest over the 
next few weeks.
