If you set <code>CompUpdate</code> to <code>true</code> Amazon Redshift applies automatic compression if the
table is empty. This applies even if the table columns already have encodings other than <code>RAW</code>. If you
set <code>CompUpdate</code> to <code>false</code>, automatic compression is disabled and existing column
encodings aren't changed. The default is <code>true</code>.
