Heikki Linnakangas df816f6ad5 Add IntegerSet, to hold large sets of 64-bit ints efficiently. ... The set is implemented as a B-tree, with a compact representation at leaf items, using Simple-8b algorithm, so that clusters of nearby values use less memory. The IntegerSet isn't used for anything yet, aside from the test code, but we have two patches in the works that would benefit from this: A patch to allow GiST vacuum to delete empty pages, and a patch to reduce heap VACUUM's memory usage, by storing the list of dead TIDs more efficiently and lifting the 1 GB limit on its size. This includes a unit test module, in src/test/modules/test_integerset. It can be used to verify correctness, as a regression test, but if you run it manully, it can also print memory usage and execution time of some of the tests.
