disposition of remaining patches

The CommitFest application currently reflects 17 remaining patches for
CommitFest 2011-01.

1. Change pg_last_xlog_receive_location not to move backwards. We
don't have complete consensus on what to do here. If we can agree on
a way forward, I think we can finish this one up pretty quickly. It's
partially being held up by #2.
2. Synchronous replication. Splitting up this patch has allowed some
progress to be made here, but there is a lot left to do, and I fear
that trying to hash out the design issues at this late date is not
going to lead to a great final product. The proposed timeout to make
the server boot out clients that don't seem to be responding is not
worth committing, as it will only work when the server isn't
generating WAL, which can't be presumed to be the normal state of
affairs. The patch to avoid ever letting the WAL sender status go
backward from catchup to streaming was committed without discussion,
and needs to be reverted for reasons discussed on that thread. An
updated version of the main patch has yet to be posted.
3, 4, 5. SQL/MED. Tom has picked up the main FDW API patch, which I
expect means it'll go in. I am not so sure about the FDW patches,
though: in particular, based on Heikki's comments, the postgresql_fdw
patch seems to be badly in need of some more work. The file_fdw patch
may be in better shape (I'm not 100% sure), but it needs the encoding
fix patch Itagaki Takahiro recently proposed. For this to be
worthwhile, we presumably need to get at least one FDW committed along
with the API patch.
6. Writeable CTEs. Tom said he'd look at this one.
7. contrib/btree_gist KNN. Needs updating as a result of the
extensions patch. This ball is really in Teodor and Oleg's court.
8, 9, 10, 11, 12, 13, 14. PL/python patches. I believe Peter was
working on these, but I haven't seen any updates in a while.
15. Fix snapshot taking inconsistencies. Tom said he'd look at this one.
16. synchronized snapshots. Alvaro is working on this one.
17. determining client_encoding from client locale. This is Peter's
patch. Peter, are you planning to commit this?
