[ 源代码： tdigest ]
软件包：postgresql-17-tdigest（1.4.3-1）
t-digest algorithm for on-line accumulation of rank-based statistics
This PostgreSQL extension implements t-digest, a data structure for on-line accumulation of rank-based statistics such as quantiles and trimmed means. The algorithm is also very friendly to parallel programs.
The accuracy of estimates produced by t-digests can be orders of magnitude more accurate than those produced by previous digest algorithms in spite of the fact that t-digests are much more compact when stored on disk.
