Last Commitfest patches waiting review

We are down to 13 patch in Needs Review state. Many of these are 
stragglers that no-one's really even looked at yet.

If we want to finish the commitfest, we'll soon have to decide what to 
do to patches that no-one cares enough about to review them.



pg_receivexlog: addition of --create/--drop to create/drop repslots
---

Magnus has promised to review this, but hasn't had the time for weeks. 
Does anyone else want to pick this up? I'm OK to wait for Magnus to 
handle this - I expect it to be a quick review and commit - but we 
should not hold up the commitfest for this.


Grouping Sets
---

There has been a lot of discussion, but no decisions. See 
http://www.postgresql.org/message-id/87vbodhtvb.fsf@news-spur.riddles.org.uk.

Would a committer be interested to take responsibility of this? If not, 
this will just linger indefinitely.


Sort support for text with strxfrm() poor man's keys
---

Peter: Are you waiting for Robert to review this? Robert, could you 
review the latest patch, please? Peter: Could you try to get rid of the 
extra SortSupport object that Robert didn't like? 
(http://www.postgresql.org/message-id/CA+TgmobDe+YDFnHTS0GWpT54-er8BPT3vx8rPshD+98CTDo25g@mail.gmail.com). 
I think it would speed up the process if you did that, instead of 
waiting for Robert to find the time.


Compression of Full Page Writes
---

This has been a ridiculously long thread, with diversions into different 
compression and CRC algorithms. Given that, the latest patch is 
surprisingly small. I don't think this is going to get any better with 
further discussion, and the patch looks OK at a quick glance, so I've 
now marked this as "Ready for Committer".


hash join - dynamic bucket count
---

Kevin: Could you review the latest patch, please?


INNER JOIN removals
---

The latest patch is significantly different from what was originally 
submitted for the commitfest, so I wouldn't feel bad just bumping this 
to the next one. I'll do that unless someone picks this up soon.

Tom: I know you're busy with the more urgent jsonb patch..  Do you think 
you would find the time to review this anytime soon? Anyone else?


event triggers: more DROP info
---

Adam: Are you planning to do more review on this? Alvaro: do you feel 
comfortable proceeding with the review you got so far?


Selectivity estimation for inet operators
---

I think there's a bug in the estimation of semi-joins, see 
http://www.postgresql.org/message-id/5423DC8D.3080206@vmware.com. But I 
think we could split this patch into two, and commit the non-join 
selectivity estimator first, as that seems OK. If no-one else steps up 
to the plate, I can do that..


add latency limit to pgbench throttling (--rate)
---

Rukh: Are you planning to review the latest patch version?

Escaping from blocked send() by pg_terminate_backend().
---

I've had a look, but I'd like to have a second opinion on this.


Fix local_preload_libraries to work as expected.
---

Peter: Could you move this forward, please?


pg_dump refactor to remove global variables
---

Peter: Can you review the latest patch, please?

Fix xpath() to return namespace definitions (fixes the issue with nested 
or repeated xpath())
---

No-one's volunteered to review this. I don't understand XML enough to 
review this, and Abhijit who was earlier signed up as reviewer said the 
same thing.

Peter: Could you take a look at this too? You've dabbled into XML stuff 
before..
