Tom Lane 25bf7f8b9b Fix possible failures when a tuplestore switches from in-memory to on-disk ... mode while callers hold pointers to in-memory tuples. I reported this for the case of nodeWindowAgg's primary scan tuple, but inspection of the code shows that all of the calls in nodeWindowAgg and nodeCtescan are at risk. For the moment, fix it with a rather brute-force approach of copying whenever one of the at-risk callers requests a tuple. Later we might think of some sort of reference-count approach to reduce tuple copying.		2009-03-27 18:30:21 +00:00
