I have just released version 7 of the PostgreSQL Buildfarm client.
As well as a few fairly minor bug fixes, it contains the following features:
. skip doing the pg_upgrade test in the TestUpgrade module if TAP
tests are configured and there is a src/bin/pg_upgrade/t directory
. add a --check-warnings command line flag that checks for warnings as
well as errors in "make" steps and reports an error if it finds any
. improve log file pickup for error detection in cross-version
. improve error messages if required https protocol support is missing.
