In src/pg/sql/13_PIA.sql https://github.com/CartoDB/crankshaft/pull/165#pullrequestreview-17287549 :

BEGIN dist := 1e999;

SELECT LEAST(dist, ST_distance(point, ST_ExteriorRing(polygon))::numeric) INTO dist;

SELECT CASE WHEN ST_Within(point,polygon) THEN 1 ELSE -1 END INTO within;

SELECT ST_NumInteriorRings(polygon) INTO holes;

IF holes > 0 THEN

FOR i IN 1..holes

LOOP

SELECT LEAST(dist, ST_distance(point, ST_InteriorRingN(polygon, i))::numeric) INTO dist;

END LOOP;

END IF;

pols := array_agg((ST_dump(polygon)).geom);

FOR j in 1..array_length(pols, 1);

@AbelVM https://github.com/AbelVM I think the CI is failing because of the semicolon on this line
