I think that's an awfully strange choice of adverb. This is, by its authors own admission, a rough cut at this, probably with very little of the optimization that could ultimately done, and it's already buying 50% on some test cases? That sounds phenomenally good to me. A 50% speedup is huge, and chances are that it can be made quite a bit better with more work, or that it already is quite a bit better with the right test case. TBH, based on previous discussion, I expected this to initially be *slower* but still worthwhile in the long run because of optimizations that it would let us do eventually with parallel query and other things. If it's this much faster out of the gate, that's really exciting. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
