Crash on aurora postgres topology add_polygon

[robe]

The performance suite is failing on aurora postgres in a couple of cases.

In the topology case it crashes

        This probably means the server terminated abnormally
        before or while processing the request.
psql:pgtap/topology/add_polygon.sql:13: fatal: connection to server was lost
Dubious, test returned 2 (wstat 512, 0x200)

The add_linestring was okay except for exceeding time limits

data

CREATE EXTENSION postgis_tiger_geocoder CASCADE;

Load data with psql from Where state boundaries are the ones in - ​http://postgis.net/extra/test-data/tiger_national.sql.bz2

Test

SELECT topology.CreateTopology('topoperf', 4269) ;
CREATE TABLE topoperf.polygon
AS SELECT (ST_Dump(geom)).geom AS g FROM (SELECT the_geom AS geom FROM tiger.state) AS f;

SELECT topology.TopoGeo_addPolygon('topoperf', g)
  FROM topoperf.polygon;

I tested on RDS running and that passed fine including the timing

I'm going to isolate further and check other systems.
