This issue is environment-sensitive, where the SSL tests could fail in various way by feeding on defaults provided by sslcert, sslkey, sslrootkey, sslrootcert, sslcrl and sslcrldir coming from a local setup, as of ~/.postgresql/ by default. Horiguchi-san has reported two failures, but more advanced testing from me (aka inclusion of garbage SSL configuration in ~/.postgresql/ for all the configuration parameters) has showed dozens of failures that can be triggered in the whole test suite. History has showed that we are not good when it comes to address such issues, fixing them locally like in dd87799, and such problems keep appearing. This commit strengthens the entire test suite to put an end to this set of problems by embedding invalid default values in all the connection strings used in the tests. The invalid values are prefixed in each connection string, relying on the follow-up values passed in the connection string to enforce any invalid value previously set. Note that two tests related to CRLs are required to fail with certain pre-set configurations, but we can rely on enforcing an empty value instead after the invalid set of values.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
