Tom Lane dad4cb6258 Improve tuplestore.c to support multiple concurrent read positions. ... This facility replaces the former mark/restore support but is otherwise upward-compatible with previous uses. It's expected to be needed for single evaluation of CTEs and also for window functions, so I'm committing it separately instead of waiting for either one of those patches to be finished. Per discussion with Greg Stark and Hitoshi Harada. Note: I removed nodeFunctionscan's mark/restore support, instead of bothering to update it for this change, because it was dead code anyway.		2008-10-01 19:51:50 +00:00
