Hello there, first I have written a wall of text, previewed it and then the forum went grey and all of the text has gone - ARRRRRRRRRRRRR!
In short: I have read some papers about different spatial indices in the last days. The standard R-tree can be improved in various ways or even replaced by a quad-tree. In one of the upcoming PostgreSQL versions they will probably have a quad-tree based SP-GiST implementation. Early proto-typing shows a speedboost of a factor of 6 in several bounding box queries. In Neo4j there are less spatial operations based on an index compared to a relational database and therefore it should be easier to find an appropriate index (which hopefully will speed up some spatial operations). In the course of my master thesis (which starts next week - wish me luck and success) I could have a look into this. So before everything is gone again - DOOOOOOOOOOOH - I finish this now...
