Another point perhaps worth considering after a second look: how about
pg_ci_base.conf?  We have the following line there, exposing this
configuration with TEMP_CONFIG:
src/tools/ci/pg_ci_base.conf:log_line_prefix = '%m [%p][%b] %q[%a][%v:%x] '

The two other ones are:
src/test/perl/PostgreSQL/Test/Cluster.pm: '%m [%p] %q%a '
src/test/regress/pg_regress.c: '%m %b[%p] %q%a '

Perhaps it would be better to apply the same configuration as the CI
by default at the end?  The difference is that the CI exposes
[virtual] XIDs.  I've never used this information for debugging, but
that may be worth considering for consistency?  This would make easier
checks across the buildfarm, the CI or local machines when looking for
differences in the logs with the same tests.

(I was incorrect previously about CI not using backend_type upthread.)
