postgresql-17-tdigest
t-digest algorithm for on-line accumulation of rank-based statistics
UnsupportedCommand lineDevelopment
Unsupported
The PostgreSQL server, and the extensions that run inside it, needs a System V shared memory segment even when set to use mmap, and Android refuses it (initdb fails on a device, with and without Breadstick's shared-memory library).

About postgresql-17-tdigest
From Debian's package description
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.
