Demystifying Database Performance for Developers
Shameless plug(s). To address both the problems you described, I have developed the following Postgres extensions.
Index Adviser can be used to automatically analyze your workload, and it will suggest the indexes that might help your queries perform better.
Postgres Plan Guarantee (under development) helps you generate+freeze a plan, and ensure that the Query Optimizer will never pick a different plan for your query.
Postgres Index Advisor: https://github.com/DrPostgres/pg_adviser
Postgres Plan Guarantee: https://github.com/DrPostgres/pg_plan_guarantee
- New extension: pg_plan_guarantee – Guarantee that your (query) plans will never change
- Show HN: Pg_plan_guarantee – Guarantee that your (query) plans will never change

Demystifying Database Performance for Developers
I highly recommend "How Query Engines Work" by Andy Grove (author of the Apache Datafusion Query Engine + Apache Ballista Distributed scheduler)
It's written in Kotlin and is very intelligible + succinct (99 pages):

Databases, Types, and the Relational Model. The Third Manifesto [pdf]
https://leanpub.com/how-query-engines-work. It covers a fair chunk of DB technology but not storage. Definitely check out their repository at https://github.com/andygrove/how-query-engines-work/tree/mai... .
A companion to DDIA would be https://www.amazon.com/Database-Internals-Deep-Distributed-S... (especially its treatment of LSM trees which is harder to come by).
