Tom Lane 08e1eedf24 Fix performance problem when building a lossy tidbitmap. ... As pointed out by Sergey Koposov, repeated invocations of tbm_lossify can make building a large tidbitmap into an O(N^2) operation. To fix, make sure we remove more than the minimum amount of information per call, and add a fallback path to behave sanely if we're unable to fit the bitmap within the requested amount of memory. This has been wrong since the tidbitmap code was written, so back-patch to all supported branches.		2011-08-20 14:51:02 -04:00
