The UPSERT logic uses accounts.first_activity which refers to the existing row value, but in SQL the table alias inside DO UPDATE should reference the target table. The correct syntax should be runtime_accounts.first_activity or the query should maintain consistency with the alias used in the INSERT clause.

Suggested change

	SET first_activity = LEAST(accounts.first_activity, excluded.first_activity)`
	SET first_activity = LEAST(runtime_accounts.first_activity, excluded.first_activity)`
