postgresql-16-tdigest binary package in Ubuntu Noble riscv64

 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.
