Using directly psql commands in the tests is not a good idea as it
makes the client-side execution more sensitive to the environment.
src/test/perl/PostgreSQL/Test/Cluster.pm does the same work, in the
wanted way, so it would be better to rely on it (see 384f1ab for one
recent issue). A test with a minimal timeout also takes time, making
for slower tests on faster machines.
Hmm. Do you think that a test based on Cluster::psql and stdout would
actually be able to do the work or would the redirection done in the
INIT block of Utils.pm prevent that? Contrary to the code path of
pg_recvlogical, Cluster::psql would use directly IPC::Run, and not
redirect stdout to the test log file.
I would stick a test in one of the existing test suites, to not create
an extra cluster and reduce its run time.
