Use getdate instead of current_timestamp

[tjengel]

This pr fixes issue #109

[drewbanin]

I think we'll want to preserve current_timestamp in the default implementation, but you can totally provide a redshift-specific implementation similar to the bigquery one below. That could just look like:

{% macro redshift__current_timestamp() %}
  getdate()::{{dbt_utils.type_timestamp()}}
{% endmacro %}

The default implementation here is going to be used by other databases like Snowflake and Postgres which do not (AFAIK) support the getdate() function.

Thanks for making this PR @tjengel! I just made a quick comment - once that's addressed I can kick off a CI build here :D

@drewbanin I was starting to suspect I'd need to go that route. I found the sample profiles.yml file. What do I need to do to get that setup to run the tests locally?

[drewbanin]

We have some (admittedly very light) docs for this over here: https://github.com/fishtown-analytics/dbt-utils/tree/master/integration_tests

You'll want to configure a profile: in your ~/.dbt/profiles.yml file named integration_tests, and then you'll want to define a target in that profile called redshift.

Once that's done, you can try running make test-redshift from the integration_tests directory. That should kick off a dbt compile, seed, run, and test in order.

That sample profiles.yml file you're referencing (this one, right is used in CI builds - you won't actually want to put your credentials in there! Always keep your creds outside of git repos -- the ~/.dbt/profiles.yml is located really far away from dbt project code to make sure it never gets committed by accident :D

Let me know if there's anything else I can help out with here

[drewbanin]

This CI build failed because of an issue with the snowflake-connector-python library. I just kicked off a new build to see if that fixes things. Once the tests pass, this will be ready to merge!

We're going to cut an 0.14.4 release of dbt which addresses this Snowflake issue - going to re-run this once that version is live.
