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.

def audit_html_files(db, cl, nodeid, newvalues):
    if 'type' in newvalues and newvalues['type'] == 'text/html':
        newvalues['type'] = 'text/plain'
    

def init(db):
    db.file.audit('set', audit_html_files)
    db.file.audit('create', audit_html_files)
