Tom Lane 2a6ebe70fb Fix contrib/seg's GiST picksplit method. ... This patch replaces Guttman's generalized split method with a simple sort-by-center-points algorithm. Since the data is only one-dimensional we don't really need the slow and none-too-stable Guttman method. This is in part a bug fix, since seg has the same size_alpha versus size_beta typo that was recently fixed in contrib/cube. It seems prudent to apply this rather aggressive fix only in HEAD, though. Back branches will just get the typo fix. Alexander Korotkov, reviewed by Yeb Havinga		2010-12-15 21:24:47 -05:00
