Buildfarm client 4.11 released

Version 4.11 of the PostgreSQL Buildfarm client has been released. It
can be downloaded from
<http://www.pgbuildfarm.org/downloads/releases/build-farm-4_11.tgz>

Changes since 4.10:

* Turn down module cleanup verbosity
* Add check for rogue postmasters.
* Add pseudo-branch targets HEAD_PLUS_LATEST and HEAD_PLUS_LATEST2.
* Use Digest::SHA instead of Digest::SHA1.
* Make directory handling more robust in git code.
* Move web transaction into a module procedure.
* Switch to using the porcelain format of git status.
* Provide parameter for core file patterns.
* Use a command file for gdb instead of the -ex option

The web transaction and Digest::SHA changes have allowed the removal of
a couple of long-standing uglinesses on the system. In almost all cases,
the config parameter "aux_path" and the separate run_web_transaction.pl
script are now redundant (the exception is older Msys systems).

Enjoy

cheers
