support for optimizer hints in PostgreSQL
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-pg-hint-plan
From Debian's package description
PostgreSQL uses a cost-based optimizer that uses data statistics, not static rules. The planner (optimizer) estimates costs of each possible execution plans for a SQL statement, then executes the plan with the lowest cost. The planner does its best to select the best execution plan, but it is far from perfect, since it may not count some data properties, like correlation between columns.
pg_hint_plan makes it possible to tweak PostgreSQL execution plans using so-called "hints" in SQL comments, like /*+ SeqScan(a) */.
