Pg_hint_plan: Force PostgreSQL to execute query plans how you want
Okay so it isn't entirely clear to me, can the pg_hint_plan extension (linked in the OP) do the simple thing where we specify, for each table, which index to use?
I can't find it here
https://github.com/ossc-db/pg_hint_plan/blob/master/docs/hin...
Because, the mssql WITH(INDEX()) is simple and intuitive. This hint table stuff seems complicated, and it's unclear to me if they can do the simple thing

10,000x Speedup for Postgres Queries: How to Make a Smart Optimizer More Stupid
I really wish the PostgreSQL core team would acknowledge that their stance on that hurts more than helps. Even Oracle with decades of engineering behind it doesn't get execution plans correct 100% of the time and provides a way to tune query execution via hints.
However, TIL that https://github.com/ossc-db/pg_hint_plan exists so that will probably become a standard thing I deploy.

Predictable plans with pg_hint_plan full hinting
With PostgreSQL, the extension to do it, pg_hint_plan is really good, but not widely used because not included in the core, not even in contrib. The consequence is that people install it only when needing it, without the time to learn hot to hint properly, may think that "my hint is not used" and give up.

How Postgres Chooses Which Index to Use for a Query
there is a maintained index hint extension: https://github.com/ossc-db/pg_hint_plan - at least as far as 13 (and likely 14).
if we're going to talk about index functionality that would be good and effective for Postgres, an index across all partitioned tables (both normal and unique) would be very much welcomed.
the problem is finding someone to maintain it for life.
