Recently I read that one of the distinctions between a standard database and a columnar one, which led to an increase in its efficiency, was and I quote:
"Only relevant columns are retrieved (A row-wise database would pull all columns and typically discard 80-95% of them)" Is this true of PostgreSQL? That eventhough my query does not call for a column it is still pulled from the table row(s). I know that my client via the JDBC does not contain the data in the ResultSet for the column, because of the packet monitoring I have done on queries. danap -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
