Oracle Auto indexes missing after ora2pg migration? Look at CONSTRAINT_INDEX
It seems that Oracle customers started using the Auto Index feature. I can see that when they migrate to YugabyteDB. YugabyteDB Voyager is a tool to ease the migration of schema and data. As YugabyteDB is PostgreSQL compatible, ora2pg is used when the source is Oracle. It extracts the schema and data. Some customers moving from Oracle ATP managed service (Autonomous Transaction Processing) reported that a few indexes were not extracted: the ones that have been created automatically by the Automatic Indexing feature of Oracle 19c.

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
What are some alternatives?
pg_ivm - IVM (Incremental View Maintenance) implementation as a PostgreSQL extension
plpgsql_check - plpgsql_check is a linter tool (does source code static analyze) for the PostgreSQL language plpgsql (the native language for PostgreSQL store procedures).
