[I] Trino embedded rows lose their column names [superset]
ilsaloving opened a new issue, #30979:
URL: https://github.com/apache/superset/issues/30979
### Bug description
I am using Trino to connect to Opensearch since Superset doesn't directly support it yet.
When I do a query that contains embedded rows, superset does not display the headers for those rows, showing only "NULL".
I opened a ticket with Trino and they said it has to do with how Superset is calling the API.

### Screenshots/recordings
### Superset version
master / latest-dev
### Python version
I don't know
### Node version
16
### Browser
Chrome
### Additional context
Actually using 4.0.2 because I haven't been having difficulties trying to extend the docker image.
Logs did not indicate any errors.
### Checklist
- [X] I have searched Superset docs and Slack and didn't find a solution to my problem.
- [X] I have searched the GitHub issue tracker and didn't find a similar bug report.
- [X] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section.

I think the previous comment effectively answers this, and it's been 5 months since the last comment, so I'll close it as completed. Holler if this needs a revisit.

For more context, we (trino python client maintainers) had been unable to find a standard way to expose field names for structural types (ROW in Trino's case, similar to STRUCT in BigQuery for example) so we implemented something in https://github.com/trinodb/trino-python-client/pull/335.
Superset can use those methods to retrieve the field names for nested types. Note that we don't use a dict to represent row types because the semantics are different and some valid ROW values cannot be represented as a dict and round-trip and equality becomes problematic so we are not open to changing that decision.
