Tom Lane 29e25a6b1e Fix incompatibilities with libxml2 >= 2.12.0.
libxml2 changed the required signature of error handler callbacks
to make the passed xmlError struct "const".  This is causing build
failures on buildfarm member caiman, and no doubt will start showing
up in the field quite soon.  Add a version check to adjust the
declaration of xml_errorHandler() according to LIBXML_VERSION.

2.12.x also produces deprecation warnings for contrib/xml2/xpath.c's
assignment to xmlLoadExtDtdDefaultValue.  I see no good reason for
that to still be there, seeing that we disabled external DTDs (at a
lower level) years ago for security reasons.  Let's just remove it.

Back-patch to all supported branches, since they might all get built
with newer libxml2 once it gets a bit more popular.  (The back
branches produce another deprecation warning about xpath.c's use of
xmlSubstituteEntitiesDefault().  We ought to consider whether to
back-patch all or part of commit 65c5864d7 to silence that.  It's
less urgent though, since it won't break the buildfarm.)

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.
