Cancelling query send does not cancel query

[PadenZach]

I'd expect ctrl-c or ctrl-d that cancels a query in the foreground, to also cancel that query on the backend (the postgres server).

for example:

postgres> SELECT some_long_running_query();
^C^Ccancelled query
postgres> select 1;
sending query failed: another command is already in progress
Time: 0.004s
postgres>
A transaction is ongoing. Choose `c` to COMMIT, `r` to ROLLBACK, `a` to abort exit, `force` to exit anyway. [a]: a
postgres> select 1;
