Can we do something hacky to get these tests to pass? Let's just not configure this model for Postgres, making it use the view materialization instead

Suggested change
{{
{% if target.type != 'postgres' %}
{{
...
}}
{% endif %}

^ I guess this fails during parsing? Boo. Might be worth just implementing that if/else block

It turns out that the circlei script doesn't run the makefile, I just made the circle config match.

config(
materialized = 'insert_by_period',
period = 'month',
timestamp_field = 'created_at',
start_date = '2018-01-01',
stop_date = '2018-06-01')
}}

with events as (
select *
from {{ ref('data_insert_by_period') }}
where __PERIOD_FILTER__
)

select * from events
