Tom Lane 1a5c450f30 When truncating a relation in-place (eg during VACUUM), do not try to unlink ... any no-longer-needed segments; just truncate them to zero bytes and leave the files in place for possible future re-use. This avoids problems when the segments are re-used due to relation growth shortly after truncation. Before, the bgwriter, and possibly other backends, could still be holding open file references to the old segment files, and would write dirty blocks into those files where they'd disappear from the view of other processes. Back-patch as far as 8.0. I believe the 7.x branches are not vulnerable, because they had no bgwriter, and "blind" writes by other backends would always be done via freshly-opened file references.		2006-11-20 01:07:56 +00:00
