This commit adds new parameter to VACUUM command, TRUNCATE, which specifies that VACUUM should attempt to truncate off any empty pages at the end of the table and allow the disk space for the truncated pages to be returned to the operating system. This parameter, if specified, overrides the vacuum_truncate reloption. If neither the reloption nor the VACUUM option is used, the default is true, as before.
