> * Greenplum version or build
> PostgreSQL 8.4.0 (Greenplum Database 6.0.0-alpha.0+dev.2546.ga5289153da build
> dev-oss)
> * Problem
> MADlib creates a function named sum in the madlib schema which throws an
> exception for create table. Note this only fails for gpdb6 and not for
> gpdb4/5 .
> This error was found by MADlib install-check tests. An issue has been opened
> on gpdb's github repository. https://github.com/greenplum-db/gpdb/issues/4185
> * Steps to reproduce the behavior
> {code}
> createdb test
> psql test
> psql (8.4.0)
> Type "help" for help.
