Ready for RC3?

What are the open issues before we can release an RC3? I
don't know of any except the btree problem OSDL found. Is
that fixed? Are their others?

There is the issue with shared mem on Win2003 that came up the other
day. I don't think it's a general error, but rather something
environment specific. (I've had several reports of ppl with fairly large
databases in production on win2003 that don't have this problem). But
it'd be good to have confirmation on that. If we could give that one a
couple of days, it would be good, but it's not a showstopper.

There sill may be an issue with the statistics collector resetting
randomly on a win32 server under heavy load. I have noticed this on
multiple servers but it hasn't been confirmed by anybody else.

I just confirmed this an a dual Opteron box running *win2k* on a
realease candidate built less than a week ago. :-(. I was trying to
upgrade a production server to retest the statistics collector...I'm
going to try a fresh compile but may have to revert back to beta5.

FATAL: could not attach to proper memory at fixed address:
shmget(key=5432001, addr=00BB0000) failed: Invalid argument

No; we haven't seen a test case yet, or even any details except the
error message.

FWIW, I think it's highly likely that whatever bug Mark has found exists
also in 7.4 --- so it's unclear that it is a reason to hold up RC3.
I think that the error must be coming out of btree page deletion during
VACUUM, and that code hasn't changed materially since 7.4.

Aside from the Windows issues mentioned, I'm somewhat concerned about
the "schemas missing after initdb" problem that the one guy in Hungary
reported. But considering that no one else has seen it, it might be a
bug in his compiler or some such. He was running suse 7 on s390, which
is a pretty old release of suse I believe, and likely not one with well
wrung out s390 support. (I tried to reproduce using current Red Hat on
s390 with same locale, but no dice.)

I doubt that size of database has anything at all to do with this.

Is there a way to determine current end of ordinary memory in Windows?
(Something akin to sbrk(0) on Unix.) It would be interesting to get the
complainant to try it with some code added that prints out the memory
end address both just before the postmaster creates the shmem segment,
and just before the child process tries to attach to it. (Maybe these
are the same place in the code, don't recall for sure.)
