Yes - PIVOT is not in standard now. But it could be in standard. It isn't replaceable with GROUPING SETS - It is total different.

[GENERAL] PIVOT tables and crosstab
Hi Are there any plans to embed crosstab within the main release of Postgres, rather than as a Contrib component. Also, are there plans to enhance crosstab along the lines of Oracle 11g of pivot command?

Sometimes downstream packagers fail to include them or break them into a separate, optional package, but they're nonetheless part of the official source code release. -- Greg Smith2ndQuadrant Baltimore, MD PostgreSQL Training, Services and Support g...@2ndquadrant.com www.2ndQuadrant.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
