Michael Paquier e688cfc2bc Fix incompatibility with libxml2 >= 2.14
libxml2 has deprecated the members of xmlBuffer, and it is recommended
to access them with dedicated routines.  We have only one case in the
tree where this shows an impact: xml2/xpath.c where "content" was
getting directly accessed.  The rest of the code looked fine, checking
the PostgreSQL code with libxml2 close to the top of its "2.14" branch.

xmlBufferContent() exists since year 2000 based on a check of the
upstream libxml2 tree, so let's switch to it.

Like 400928b83b, backpatch all the way down as this can have an impact
on all the branches already released once newer versions of libxml2 get
more popular.

The PostgreSQL contrib tree
---------------------------

This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree.  This does not preclude their
usefulness.

User documentation for each module appears in the main SGML
documentation.

When building from the source distribution, these modules are not
built automatically, unless you build the "world" target.  You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.

Some directories supply new user-defined functions, operators, or
types.  To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command.  In a fresh database,
you can simply do

    CREATE EXTENSION module_name;

See the PostgreSQL documentation for more information about this
procedure.
