This fails the tests under the undefined behaviour sanitizer. Se e.g. https://cirrus-ci.com/task/6313371143766016 There are a lot of crashes due to ubsan failures. One of them is: [21:22:15.116] stderr: [21:22:15.116] # Failed test 'newline in dbname: stderr matches' [21:22:15.116] # at /tmp/cirrus-ci-build/src/bin/pg_dump/t/003_pg_dump_with_server.pl line 29.
