        Enable additional test suites, which are not run by default because
        they are not secure to run on a multiuser system, require special
        software to run, or are resource intensive.  The argument is a
        whitespace-separated list of tests to enable. See
        <xref linkend="regress-additional"/> for details. If the
        <envar>PG_TEST_EXTRA</envar> environment variable is set when the
        tests are run, it overrides this setup-time option.

        If using GCC, all programs and libraries are compiled with
        code coverage testing instrumentation.  When run, they
        generate files in the build directory with code coverage
        metrics.
        See <xref linkend="regress-coverage"/>
        for more information. This option is for use only with GCC
        and when doing development work.

        Compiles <productname>PostgreSQL</productname> with support for

        user-defined code from within the server in pre-defined code paths.
        This helps in testing and in the investigation of concurrency scenarios
        in a controlled fashion. This option is disabled by default.  See

        option is intended to be used only by developers for testing.
