| 2008-09-11 22:36:45.0 | 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. | |

Particularly since the "box" their own product comes out of is "compiled from CVS checkout". Their argument seems to be that people can learn how to drive CVS and to compile software under active development, but can't read the manual that comes with Postgres (and a release of Postgres well over a year old, at that). I didn't get any further in reading the claims, because it's obviously nothing more than a marketing effort using the principle that deriding everyone else will make them look better. Whether they have a good product is another question entirely.

It would be nice to know about the data, queries, and the expected results of their tests just so we could see this for ourselves. -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug -- Sent via pgsql-general mailing list (pgsql-noway@spam.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general |
