postgresql-cygwin is working fine. See the testfarm.
Just cygwin itself, cygserver - the IPC daemon - has problems.
On msgctl(IPC_INFO) the internal msg buffer struct msqid_ds *buf is
allocated at a non-writable area, IsBadWritePtr() fails. I suspect it's
a new gcc-3.4 feature, but haven't found the problem yet. gcc-3.3 fails
also. (these don't have dwarf-2 support yet, just sjlj. cygwin itself is
c++ and uses exceptions heavily.)
It works for most users out there, but not for me, this is why I didn't
did a proper beta5 cygwin release yet. A pity that no one else can
confirm my cygserver problems yet.
And I got beta4 on a fairly busy server working only with
max-connection=2, not more.
