Heikki Linnakangas 62401db45c Support unlogged GiST index. ... The reason this wasn't supported before was that GiST indexes need an increasing sequence to detect concurrent page-splits. In a regular WAL- logged GiST index, the LSN of the page-split record is used for that purpose, and in a temporary index, we can get away with a backend-local counter. Neither of those methods works for an unlogged relation. To provide such an increasing sequence of numbers, create a "fake LSN" counter that is saved and restored across shutdowns. On recovery, unlogged relations are blown away, so the counter doesn't need to survive that either. Jeevan Chalke, based on discussions with Robert Haas, Tom Lane and me.		13 years ago
