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.
