    Added Postgres CI opportunistic test case

    Added test case and support functions for CI opportunistic testing
    using a PostgreSQL database, as part of our postgresql as a first
    class citizen effort.

    rebased again on top of test migration with data framework

    clean up debug, and ensure pg will fail to connect gracefully

    fix previous migration test which was inserting a key by id, which
    postgresql doesn't like, as it doesn't adjust the autoincrement
    counter.

    added driver to connection string for mysql

    Updated comment to expose how to do this on pg easily

    Fixes:
    bug 1084567
