Hi all
As mentioned here, there has been a discussion about $subject and the
fact that it may be rather useless:

--disable-strong-random is also untested in the buildfarm.

When I build this patch against master (4203842), it builds, but breaks

tl;dr: I'd like to teach btrees to support returning ordered results
where the ordering is only a suffix of the index keys and the query
includes a scalar array op qual on the prefix key of the index.
Suppose we have the following schema:

I think 0001 with complete keyword lookup replacement is in decent
enough shape to post. Make check-world passes. A few notes and
caveats:

-ECPG keyword lookup is a bit different in that the ec

Further to this ... I was just doing some measurements to see how much
it'd add to backend startup time if we start using pg_strong_random()
to set the initial random seed. The answer, at least on my slightly
long-in-the-tooth RHEL6 box, is "about 25 usec using /dev/urandom,

It's not clear to me that that is what is usually wanted.
The point of the post-upgrade analyze script is specifically to do the
analyze in a gentle fashion.
Hi all,
I was just modifying configure.in for another patch, then tried to
generate the new configure with autoconf on Debian. However I am
bumping into some noise in the process. First the state associated to
runstatedir support gets generated, which makes little sense for
