Tom Lane d22a09dc70 Support GiST index support functions that want to cache data across calls. ... pg_trgm was already doing this unofficially, but the implementation hadn't been thought through very well and leaked memory. Restructure the core GiST code so that it actually works, and document it. Ordinarily this would have required an extra memory context creation/destruction for each GiST index search, but I was able to avoid that in the normal case of a non-rescanned search by finessing the handling of the RBTree. It used to have its own context always, but now shares a context with the scan-lifespan data structures, unless there is more than one rescan call. This should make the added overhead unnoticeable in typical cases.		2011-09-30 19:48:57 -04:00
