wal_buffers_full tracks the number of times WAL buffers become full, giving hints to be able to tune the GUC wal_buffers. Up to now, this information was only available in pg_stat_wal. With this field available in WalUsage since eaf502747bac, exposing it in pg_stat_statements is straight-forward, and it offers more granularity at query level. pg_stat_statements does not need a version bump as one has been done in commit cf54a2c00254 for this development cycle.

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.
