I took a brief look through this and it seems reasonable. Two
minor comments:
* In the docs section beginning "Context managers syntax using the with
keyword", could we drop that entire <sect2>? It seems like it's now not
saying much more than "you can use this standard python feature", which
is hardly surprising information.
* I'm not sure it's a good idea to remove the test case you removed
from plpython_subtransaction.sql. We still need to support user
code written that way, don't we?

That section points out the existence of the subxact.enter() and
subxact.exit() methods. New code wouldn't need to use those, but
someone might find them in old code, so it would be good to have them at
least mentioned somewhere. Maybe it could be rewritten, but I hesitate
to remove it completely.

The main purpose of that test case was that older Python versions can
test this functionality at all, because most of the rest of the file
would fail with Python syntax errors around the "with" keyword. With
newer Python versions there is IMO no need to test both the "with"
variant and the equivalent __enter__+__exit__ variant separately,
because that would just show that Python itself works correctly. Then
again, we could keep it for completeness and clarity.

It appears that the removal of old OpenSSL support is stalled or
abandoned for now, so this patch set is on hold for now as well, as far
as I'm concerned. I have committed the change of the Python exception
syntax in the documentation, though.

Yeah, the cleanup of the code related to OpenSSL 0.9.8 and 1.0.0 was
rather limited, which was disappointing, so I am still hesitating in
merging that into the tree. Doing more cleanup with the past Python
versions gives a good extra argument though, so I'll send a notice on
the OpenSSL thread here:

Since the OpenSSL patch went ahead, I have now committed this one as well.

Rémi,
please update your build farm member "locust" to a new Python version
(>=2.6) for the master branch, or disable the Python option.
Thanks.
