   Nice, the demo makes it clear: psycopg 3 cancels, the blocking C drivers 
don't. Still worth having since psycopg 3 is the default on 3.3.
   
   1. The `cancel_query` docstring says `oracledb` and `trino` work, but only 
psycopg 3 has been tested. Can you run the same check on Trino, or drop those 
two from the docstring?
   2. `execute()` sets `hook._cancel_on_interrupt`, a private attribute, from 
the operator. Please make it public on `DbApiHook` so custom hooks and 
subclasses can use it.
   
   +1 on psycopg2 and SQLite as follow-up PRs in their providers. Snowflake can 
get the same by using `_track_running_cursor` in its `_run_command`.
