Release 11 of the PostgreSQL Buildfarm client

Release 11 of the PostgreSQL Buildfarm client is now available.

The release includes numerous bug fixes plus following features:

• Allow a list of branches as positional arguments to run_branches.pl
  This overrides what is found in the config file. The list can’t include
  metabranches like ALL, nor can it contain regexes.
• improve diagnostic capture for git and fetching branches of interest
• unify config.log and configure.log
• add siginfo to gdb output
• improve test coverage
  • run check for test modules marked NO_INSTALLCHECK
  • run TAP tests for test modules that have them
  • run TAP tests for contrib modules that have them
• explicitly use “trust” with initdb
