this particularly fixes clickhouse backend
* docs: added clickhouse
* models: allow using secondary dttm columns as constraints

When adding a Redshift database, the docs said to use a connection
string that started with `redshift+psycopg2://...`, but this results
in a Python error from how SQLAlchemy executes the `get_schema_names`
method (first reported [here](https://github.com/airbnb/superset/issues/2364#issuecomment-284705179)).
The fix is to use `postgresql+psycog2://...` for the Redshift connection
string.
