Andres Freund 84ad4b036d Reduce memory usage of targetlist SRFs. ... Previously nodeProjectSet only released memory once per input tuple, rather than once per returned tuple. If the computation of an individual returned tuple requires a lot of memory, that can lead to problems. Instead change things so that the expression context can be reset once per output tuple, which requires a new memory context to store SRF arguments in. This is a longstanding issue, but was hard to fix before 9.6, due to the way tSRFs where evaluated. But it's fairly easy to fix now. We could backpatch this into 10, but given there've been fewc omplaints that doesn't seem worth the risk so far.
