offer PostgreSQL storage for pointerdb (#440) ..although it ought to work for other storage.KeyValueStore needs as well. it's just optimized to work pretty well for a largish hierarchy of paths. This includes the addition of "long benchmarks" for KeyValueStore testing. These will only be run when -test-bench-long is added to the test flags. In these benchmarks, a large corpus of paths matching a natural ("real-life") hierarchy is read from paths.data.gz (which you can get from https://github.com/storj/path-test-corpus) and imported into a particular KeyValueStore. Recursive and non-recursive queries are run on it to detect performance problems that arise only at scale. This also includes alternate implementation of the postgreskv client, which works in a less-bizarre way for non-recursive queries, but suffers from poor performance in tests such as the long benchmarks. Once this alternate impl is committed to the tree, we can remove it again; I just want it to be available for future reference. 2018-10-25 18:11:28 +01:00			`// See LICENSE for copying information.`
