It seems the latest libpq5 (9.2.4-2) installs /bin/cygpq-5.dll, but at least xemacs fails to find this lib (it looks for cygpq.dll) and fails to load. Downgrading libpq5 to 8.2.11-1 solves the xemacs issue for me. Before I downgraded I tried to symlink cygpq.dll to cygpq-5.dll, but this caused xemacs to silently fail to start. So I gather libpq 9 is not binary compatible with libpq 8.
