Great — Postgres optimizations in Rails.

Tell me a bit about your current background and your goal so I can tailor this: select the option that best matches your level, choose what depth you want, and add any specifics.

1) Your experience level with Rails/Postgres (pick one):

Beginner — new to Rails/Postgres
Intermediate — comfortable with Rails, some SQL
Advanced — production Rails apps and DB tuning

2) Desired depth/goal (pick one):

Quick wins — easy config/queries to improve performance
Profiling & diagnostics — find bottlenecks
Schema & indexing strategy
Advanced tuning — vacuum, autovacuum, planner, connection pooling

3) Which of these apply? (multi-select)

Large tables (tens of millions of rows)
Occasional slow queries
High concurrency / many connections
Background jobs causing DB load
Read replicas / HA

4) Optional: Briefly describe any specific pain points or constraints (one short sentence)

5) Anything else that would help me tailor this to you?
