Alvaro Herrera 3b0347b36e Move the tuple freezing point in CLUSTER to a point further back in the past, ... to avoid losing useful Xid information in not-so-old tuples. This makes CLUSTER behave the same as VACUUM as far a tuple-freezing behavior goes (though CLUSTER does not yet advance the table's relfrozenxid). While at it, move the actual freezing operation in rewriteheap.c to a more appropriate place, and document it thoroughly. This part of the patch from Tom Lane.		2007-05-17 15:28:29 +00:00
