I've reproduced the issue on local and confirmed the root cause; two
background psql sessions in the TAP test run with ON_ERROR_STOP=1 and
got canceled by pg_cancel_backend(), so psql exited as soon as the
cancelation error arrived. I've attached the patch that fixes the
problem. I'm waiting for CI to check if the tests still pass on other
environments.
