• Criação de Procedure para Cálculo da distância entre dois pontos usando a fórmula de Haversine em PostgreSQL:

CREATE OR REPLACE FUNCTION distancia_km(lat1 NUMERIC, lng1 NUMERIC, lat2 NUMERIC, lng2 NUMERIC) RETURNS DOUBLE PRECISION AS $BODY$

SELECT 6371 * acos(
    sin( radians($1) ) * sin( radians( $3 ))
      + cos( radians($1) ) * cos( radians( $3 )) * cos(radians($4) - radians($2))  )
as distance;

$BODY$

LANGUAGE sql IMMUTABLE
COST 100;

• How to run the test suite

• Services (job queues, cache servers, search engines, etc.)

• Deployment instructions
