Note here: we can just compare the result with '2'.

Fixed and backpatched these two at the end as they could mask bugs, on
the branches where they matter.

Not sure that the bits in 010_pg_basebackup were an improvement. In
004_test_parser_perf, the result is indeed empty, but it's a matter of
the result returned by IPC::run::run.

-ok($node->log_contains(qr/no SSL error reported/) == 0,
+is($node->log_contains(qr/no SSL error reported/), 0

The CI was failing with the change in the SSL tests, as of:
[05:03:12.647] # at
/tmp/cirrus-ci-build/src/test/ssl/t/001_ssltests.pl line 127.
[05:03:12.647] # got: ''
[05:03:12.647] # expected: '0'

There was already a lot of content already. So I have left this one
out for the moment and applied a good chunk of the rest with some
indentation.
