def upgrade():
    # The ps_endpoints identify_by column has always been a comma separated
    # list of enum values.  This is better represented as a string anyway to
    # avoid database compatibility issues.  Also future changes are likely
    # to allow loadable endpoint identifier names and negating fixed enum
    # benefits.
