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.

Beyond SQL: A relational database for modern applications
> In other words, there is still a (lossy) translation layer, it just happens to be in the RDBMS rather than in-app.
It's not lossy if your application can guarantee a json <-> datatype roundtrip and the json is validated with jsonschema (generated by your application)
In Rust it's something like this
https://serde.rs/ to do the data type <-> json mapping
https://docs.rs/schemars/latest/schemars/ to generate jsonschema from your types
https://github.com/supabase/pg_jsonschema to validate jsonschema in your database (postgres). with this setup it's interesting (but not required) to also use https://docs.rs/jsonschema/latest/jsonschema/ to validate the schema in your application

FerretDB, a truly open-source MongoDB alternative
Pretty exciting!
What about optionally validating some columns with jsonschema? Perhaps using https://github.com/supabase/pg_jsonschema - is using other postgres extensions supported in FerretDB? (if not, maybe it's feasible to incorporate the code of pg_jsonschema in FerretDB?)

Ask HN: Do you use JSON Schema? Help us shape its future stability guarantees
I'm not currently using it, but I'm strongly considering validating json in postgres with https://github.com/supabase/pg_jsonschema - which uses the https://docs.rs/jsonschema/latest/jsonschema/ Rust crate
So I'm not sure if my feedback is valid but, I sure hope that the jsonschema crate follows the spec! Otherwise I'll never use jsonschema but instead something-not-exactly-jsonschema. In other words.. you better not break anything.

Features I'd Like in PostgreSQL
Sounds dumb, but I want JSON field schema validation. I added a JSON column for flexible data, and although I'm happy with its flexibility, I kinda hope I can validate the JSON data structure. Recently I just found an extension [1] and will try soon.
