[postgis-users] PostGIS functions not working on AWS via Lambda function

[Giuseppe Broccolo]

Ok, as I told befire lambda functions should rely on RDS instances. Once
you open a connection
to the DB through psycopg, enable the Postgis extension with

cur.execute("CREATE EXTENSION postgis")

then try to run your UDF.
