Essentially results in a SQL query of: CALL "stg_customervip"."sp_stg_customer"(37::bigint, '2020-01-15 05:52:31'::timestamp)
If I take that query and run it directly in redshift it runs successfully but via psycopg2 it returns:

psycopg2.errors.FeatureNotSupported: TRUNCATE cannot be invoked from a procedure that is executing in an atomic context.
HINT: Try calling the procedure as a top-level call i.e. not from within an explicit transaction block. Or, if this procedure (or one of its ancestors in the call chain) was created with SET config options, recreate the procedure without them.
CONTEXT: SQL statement "TRUNCATE table stg_customervip.Customer"

While that error sounds legitimate I think it might be a redherring because it does execute successfully if I do it manually against redshift.

Probably if you run it manually you do it outside a transaction. Psycopg starts a transaction automatically (no, I don't think it's a good idea, but it's part of the specs)

http://initd.org/psycopg/docs/usage.html#transactions-control

Try setting `redshift_conn.autocommit = True` after connection creation, and do without the `commit()`s.
