Change method for settin indexer; have test_livetest for pg cleanup Add code to defer opening the indexer only if indexer is native-fts. See if this fixes the sqlite OperationalError. Also under python 2.7 (only), the db from test_livetracker when using postgres FTS didn't empty the db. This caused the following test_postgres.py test to fail. Why it only showed up on 2.7 and not any of the 3.x releases is a mystery.

try:
    from html import escape as html_escape_  # python 3

    def html_escape(str, quote=False):
        # html_escape under python 3 sets quote to true by default
        # make it python 2 compatible
        return html_escape_(str, quote=quote)
except ImportError:
    # python 2 fallback
    from cgi import escape as html_escape  # noqa: F401
