The SSL tests have always sent down a query even for scenarios where
the connection would fail, but they have used command_fails_like()
rather than PostgresNode::psql. The puzzle does not seem complete.

Yeah. Looking at the git history, that would be c757a3da.
test_access() in the kerberos tests sends a SELECT true even for
expected failures, so it seems to me that it would fail with the same
symptoms on those machines. That looks worth fixing and
backpatching.
And I need more caffeine this morning.. I missed your point that a
connection failure should pass down an undefined query string per
that. Well, the fix is simple then now that there is a single code
path for all those connection attempts.
