Обсуждение: CLUSTER micro-doc-patch

Hello All,

Doing recently the CLUSTER operation with (SELECT .. ORDER BY ...) instead
of CLUSTER I realized that that operation requires the free space equal to
twice! the size of the table size :-( (which is unfortunately a serious
drawback of the SELECT method, comparing to the plain CLUSTER for
the large tables )...

So, I send the small doc-patch saying about the space requirement of the
cluster operation using SELECT ORDER BY.

Regards,
     Sergey
