Okay, it passed now it seems so I guess this test is flaky somehow. The error message and the timing difference between failed and succeeded buildfarm run clearly indicates that the pg_sleep ran its 180 seconds to completion (so cancel was never processed for some reason). **failed case** 282/285 postgresql:libpq_pipeline / libpq_pipeline/001_libpq_pipeline ERROR 191.56s exit status 1 **succeeded case** 252/285 postgresql:libpq_pipeline / libpq_pipeline/001_libpq_pipeline OK 10.01s 21 subtests passed I don't see any obvious reason for how this test can be flaky, but I'll think a bit more about it tomorrow.
