I haven't checked the patches yet but for this problem I generally
select any other long-running test and try to normalize test timings.
What I mean is:
With patch:
postgresql:pg_waldump/001_basic 200s
pg_rewind/002_databases 455s
Without the patch:
pg_waldump/001_basic 300s
pg_rewind/002_databases 315s
After normalizing the 'without the patch' timings:
pg_waldump/001_basic 430s
pg_rewind/002_databases 455s
