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-first-last-agg
From Debian's package description
first-last-agg is a simple extension providing two aggregate functions, last and first, operating on any element type and returning the last or the first value of the group.
Since by default the ordering inside groups created by a GROUP BY expression is not defined, it is advisable to use an ORDER BY clause inside the aggregate expression (see the aggregate function syntax).
