[Pkg-postgresql-public] Bug#808325: postgresql-9.4: FTBFS: libxml2 changes

[Niko Tyni]

Package: postgresql-9.4
Version: 9.4.5-1
Severity: serious
X-Debbugs-Cc: libxml2 at packages.debian.org

This package fails to build on current sid on all architectures due to
test suite failures. This regressed with libxml2 2.9.3+dfsg1-1 and works
fine with 2.9.2+zdfsg1-4 from testing. Cc'ing the libxml2 maintainers.

The timing is rather unfortunate, as this made binNMUs for the current
Perl 5.22 transition fail, leaving postgresql-plperl-9.4 uninstallable.
