new buildfarm client release 4.8

There is a new release of the PostgreSQL buildfarm client available, It 
can be downloaded at 
<https://github.com/downloads/PGBuildFarm/client-code/build-farm-4_8.tgz>

Apart from some bug fixes, changes of note include:
 * A new --only-steps command line option, requested by Stephen Frost   (although not his patch) * A new module
TestUpgrade,which is enabled by default in the new   config file, to test pg_upgrade * Report the environment that the
clientoperates in. This will help   in debugging problems. Only values of certain white-listed   environment keys are
reportedfor security reasons. * A new make_jobs config parameter to run make in parallel * A new "check" module hook
(whichis used by the TestUpgrade module).
 

Existing users will probably want to add:
   modules => ['TestUpgrade'],

to their config files, and possibly also something like
   make_jobs => 4,


Enjoy.

cheers
