I read something from http://monetdb.cwi.nl/projects/monetdb/SQL/Benchmark/TPCH/index.html saying
that PostgreSQL can't give the correct result of the some TPC-H queries, I
wonder is there any official statements about this, because it will affect our
plane of using PostgreSQL as an alternative because it's usability. BTW I don't
think PostgreSQL performances worse because the default configuration usually
can't use enough resources of the computer, as as
memory.
